Scientists usually receive very few grants for research on the safety of vaccinations, adjuvants and other vaccine components. However, there is more than enough funds to research why people do not vaccinate, and how to make them vaccinate their children. Therefore, there are many studies characterizing "anti-vaxx" parents.
Argument: "If there were any problems with the vaccines, if they were unsafe or ineffective, doctors would know about it. But there is currently almost complete scientific consensus - vaccines are safe and effective. After all, doctors, with their long years of formal training, have probably studied vaccines much more than you could ever read on the Internet".
How should the safety of vaccines be tested? By performing randomized, double-blind, placebo-controlled clinical trials, during which the data on adverse effects experienced by the vaccine recipients is collected and compared to the control group.
We have already seen that safety of vaccines is tested without a real placebo, but only in the comparison to other vaccine, or in comparison with some other toxic compound. But this is not all. There are a few more problems with testing vaccines’ safety.
Neither CDC, nor FDA, and especially not the pharmaceutical companies, conduct studies comparing vaccinated and unvaccinated children. Here the director from CDC, being back against the wall, admits to this fact at the congressional hearing (20 seconds). (Full version)
Most people assume that a vaccine is just a weakened or killed virus/bacteria. The immune system produces antibodies for the injected killed virus, and subsequently, if the person becomes infected – his immune system can already recognize the virus and react quickly to it.
This description is simplified to such extent that one might argue that it is completely untrue.
I’m beginning the review of individual vaccines with the Human Papilloma Virus (HPV) vaccine, as it is, without doubt, the most dangerous and useless one.
If there were anything more stupid than vaccinating a teenager against HPV, it certainly would be vaccinating a newborn baby against hepatitis B.
Pertussis is caused by a bacterium, Bordetella pertussis, that settles in the airways of the respiratory tract. While the bacterium itself is not so dangerous, it secretes a toxin known as the pertussis toxin. This toxin irritates the respiratory tract and results in the release of mucus, ultimately leading to a severe cough with a characteristic sound (whoop). The cough can last for weeks, the reason why the Japanese and Chinese call this disease the "100-day cough". Although this disease can be quite unpleasant for both children and adults, it is generally not dangerous. However, for babies, especially those below the age of 3 months (those who cannot really cough to withdraw mucus), whooping cough can be fatal. In infants up to four months, about 1% of all whooping cough cases have a lethal outcome.
Unlike papilloma or whooping cough, tetanus is a really dangerous disease. Many parents, who refuse other vaccinations, still consider it necessary to vaccinate against tetanus. But what is the probability of contracting tetanus? Is it more dangerous than the vaccine? And, does the vaccine protect against tetanus?
Diphtheria, like tetanus, is also a rather dangerous disease, but what is the probability of getting sick with diphtheria in this day and age, and how effective is the vaccine?
Measles is certainly the biggest horror story. If the media is to be believed, measles are much worse Ebola.
Mumps in children is usually so mild that even WHO does not scare anyone with it. In adults, however, they say that mumps can cause severe complications. Hence it is important to vaccinate infants.
Rubella in children is even milder than mumps. However, rubella can be dangerous for pregnant women in their first trimester.
Unlike the whooping cough, when adults and children are vaccinated to protect infants, in case of rubella, infants are vaccinated to protect pregnant women. Or, to be more precise, babies are vaccinated to protect the unborn babies.
Despite the fact that poliomyelitis in developed countries has not been observed for decades, it, for some reason, continues to inspire horror.
It is believed that more people die from the flu than from all the other vaccine diseases combined. Therefore, theoretically, if there is a sense from something to get vaccinated, it's from the flu.
Hemophilus, pneumococcus and meningococcus are the three main types of bacteria that can lead to meningitis and other invasive diseases. Bacterial meningitis, unlike viral meningitis, can be very dangerous.
Pneumococcus is a common bacterium that can lead to meningitis and other invasive diseases, like hemophilia, after the onset of Hib vaccination, the incidence of hemophilic infection has temporarily decreased and the incidence of pneumococcal infection has increased. hemophilic meningitis is 3%, then the death rate from pneumococcal meningitis is 19%.
Just recently, chickenpox was a harmless childhood disease, but it becomes more dangerous each year, and soon will come the time when it will become more dangerous than measles, which is already more dangerous than Ebola.
Before the introduction of the vaccine, few people have heard of rotavirus infection, despite the fact that almost all children got infected with it.
If children and adults are vaccinated against whooping cough to protect infants, and infants get vaccinated against rubella to protect unborn infants, in case of the hepatitis A, infants get vaccinated to protect adults.
Meningococcus is the third type of bacteria causing meningitis and bacteremia. The incidence of meningococcal infection is significantly lower than the incidence of pneumococcal and Haemophilus influenzae infections, but since meningococcal vaccine is the newest licensed vaccine, meningococcus has recently become the biggest horror story.
Billions of people have been vaccinated with BCG since 1921, more than any other vaccine, but BCG is no less controversial than any other vaccine, its effectiveness has been debated so far and varies in various tests from zero up to 80% BCG are considered one of the safest vaccines, but the true statistics of such post-vaccination complications as BCG-it (lymphadenitis) and BCG-osteomyelitis are unknown.
Because of concerns about the efficacy and safety of BCG, to this day have been developed and examined on animals almost 200 new vaccines against tuberculosis, but only one of them showed better results than BCG, and it was a recombinant form of BCG itself.
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, but the vaccine contains Mycobacterium bovis, which causes tuberculosis in cows. This is because Calmette and Guerin, who named the vaccine, developed it initially for cattle, and not for humans. To this day, it is not known how important it is that the vaccine is based on M. bovis, and not on M. tuberculosis.
Calmette added bile to the culture of bacteria, so that they do not They fell and noticed that after a few months the bacterium became less virulent for guinea pigs. He continued to attenuate the bacterium in the presence of bile for 13 years, changing the nutrient medium every two weeks.
Since 1921, BCG has also begun to be done to humans. But since at that time the bacteria could not be freeze dry, they continued to be weakened in the same way and continued until 1961, changing the substrate every two weeks.
Calmette reported a decrease in virulence after 15 passages, and an even larger weakening after 215 passages. Was the bacterium weakened even more by 1961, after 1,173 passages, is unknown, since neither the original bacteria nor the original BCG of 1921 have survived.
Since 1924, BCG have begun to spread to laboratories in other countries that have continued to weaken the bacteria by that the same scheme and with the same goal - to prevent the return of virulence, while maintaining efficiency. So in different countries, BCG daughter strains were formed, which are called at the place of the laboratory (BCG Russia, Tokyo, Denmark, etc.). At present, BCG strains are prepared from lyophilized bacterial stocks that are re-suspended (added back to water) before vaccination. In most BCG vaccines, 90-95% of bacteria are dead, but in BCG Tokyo, 25% of bacteria are live. The importance of the proportion of live bacteria in the vaccine has not yet been studied. For example, do dead bacteria compensate the living? Science does not yet know the answer to this question.
What is important for a weakened vaccine is the presence of antigens in the absence of virulence. But it is known that certain strains of BCG lost antigens compared to the original bacterium. Loss of antigens is obviously undesirable, and it should be studied.
In an experiment in Czechoslovakia, the BCG-Prague strain was changed to BCG-Russia. The incidence of disseminated tuberculosis, including BCG osteitis due to vaccination, was higher in the Russian strain.
In the 1970s there was an epidemic of BCG osteitis in Sweden and in Finland, after which Finland switched to another strain, and Sweden canceled vaccination.
Have the strains of BCG changed during this time? Certainly. Is it important? Watching who to ask. The bacteriologist will be surprised if BCG has not changed significantly over half a century of cultivation in the laboratory. An official planning to vaccinate millions of babies needs more information. Is there the most effective strain of BCG? Or is it the safest? Do they differ? The answers to these questions, unfortunately, are still unknown.
Regardless of whether a certain strain of BCG will be used in the future, its genetically modified version, or an entirely new vaccine, let's hope that manufacturers will conduct clinical trials of the vaccine so that we again did not remain with the uncertainty of vaccinating millions of babies every year, without a clear understanding of its risks and benefits.
Vitamin K injection is one of the procedures almost every child undergoes immediately after birth in most developed countries. Vitamin K plays an important role in the blood clotting process, and it is believed that its deficiency can potentially lead to Vitamin K Deficiency Bleeding (VKDB)
Синдром внезапной детской смерти (СВДС или SIDS) - это неожиданная смерть здорового младенца в первый год жизни. СВДС - это ведущая причина постнеонатальной смертности в США (1 на 2000 младенцев).
СВДС - это диагноз исключения, то есть если после расследования и вскрытия не нашлась другая причина смерти - значит это СВДС. Хотя причина СВДС неизвестна по определению, как и в случае с аутизмом, точно известно, что прививки тут ни при чем.
According to the WHO, mercury is considered to be one of the ten most dangerous chemicals. According to the WHO, Mercury is especially dangerous for intrauterine fetal development and infants in early stages of life. Mercury is dangerous in elemental form (metal), as well as in inorganic (mercury chloride) and in organic (methylmercury) compounds.
However, there is one organic compound of mercury, which is so safe, that infants and pregnant women can be safely injected with it. This compound is called ethylmercury.
Начиная с 1990-х годов, количество аутистов увеличилось на несколько порядков. Причина аутизма до сих пор неизвестна, и точно известно лишь одно - вакцины не приводят к аутизму.
Впервые аутоиммунные заболевания были описаны в начале 20-го века, когда Сергей Метальников обнаружил, что если морским свинкам делать инъекции сперматозоидов, это приводит к выработке антител, которые иммобилизируют сперму. Тем не менее, существование аутоиммунных заболеваний оспаривалось вплоть до 1960-х. На сегодняшний день описаны более 100 видов аутоиммунных заболеваний. Их причина неизвестна.
