Compared to natural infection, the body produces 3 to 3.5 times the level of antibodies against the Pfizer and BioNTech coronavirus vaccine, and even in the age group over 55, the rate is 1, 8 to 2 times greater, but this is only shows the strength of the immune response, not its durability. How long the vaccine will protect against infection remains questionable. Pfizer has held a press conference on the vaccine now that it has been granted a conditional license in the European Union.
However, it is important to note that it takes 28 days for 95 percent protection to develop before someone can contract and transmit the virus. Until then, it is still worth practicing social distancing and going less to the community. However, it is not yet known how much the immunity provided by the vaccine differs from natural immunity, nor what the situation is with reinfection; Results are likely to come from clinical trials within 3-4 months.
Side effects and collision
As for the side effects, Dr. Tibor Fabó The medical director said: Messenger RNA disappears from the body within 72 hours, from then on only the body’s natural immune response takes place, so the chances of serious long-term side effects are minimal. However, Phase 3 clinical trials are not yet complete, with participants being followed for two years, which is equivalent to a clinical trial related to a conventional vaccine.
You don’t even have to worry if someone has already been infected with the virus or is just sick and getting the vaccine. The vaccine can be given in case of a mild infection, even if someone has already had the infection, but severe patients should not receive it, but the same is true for other vaccines.
The English mutation
Pfizer constantly monitors the English mutation, just like the others, for now Dr. Péter VereckeiAccording to the executive of the company, it is not necessary to modify the vaccine. If the peak protein is affected to such an extent by a mutation that requires it, the vaccine can be quickly modified, already working in 17 different strains. Therefore, it is not necessary to produce a new vaccine, but to change the current one a bit: not all mutations need a separate vaccine, but the universal vaccine will be effective against more and more viral mutations.
The diseases with which the vaccine should not be administered are decided individually by each doctor; at the moment, it is certain that a severe allergic reaction to vaccines or an allergic reaction to their components may be a reason for exclusion. But not all diseases that affect the immune system can throw someone out of line.
Pfizer representatives also drew attention to the fact that vaccine theft and counterfeiting can be real problems. Safety must be resolved by vaccination points, while counterfeit vaccines must be presented before users: Pfizer vaccines will only be available at designated public vaccination points, not in private clinics, pharmacies, or on the Internet. So any vaccine you buy there is probably a fake.
