Safety trials begin in the lab, with tests and research on cells and animals, before moving on to human studies. The principle is to start small and only move to the next stage of testing if there are no outstanding safety concerns.
But we still don’t know the origins of the Covid19! …..Are we all guineapig’s ??
Approval is only given if regulators are happy that a vaccine is safe and effective. Checks continue after approval to make sure there are no further side effects or long-term risks.
What are long term risks? How can you tell just after 2-3 years, if there will be any side effects?
Should we trust the expertise?
-Pfizer-BioNTech’s vaccine (and Moderna’s) uses bits of genetic code to cause an immune response. These are called mRNA vaccines. They do not alter human cells, but merely present the body with instructions to build immunity to Covid.
-The Oxford-AstraZeneca vaccine uses a harmless virus altered to look a lot more like the pandemic virus.
Vaccines sometimes contain other ingredients, like aluminums, that make the vaccine stable or more effective. This sound strange to a normal person, like me….What about the metal detectors??
What about allergies?
Allergic reactions to vaccines are rare. For any approved vaccine, the ingredients are listed. There have been serious but treatable allergic reactions in a very small number of people given the Pfizer-BioNTech vaccine. But in long term, we know very little about this.
More are re-infected in covid-19.
It is becoming increasingly common to suffer from covid-19 again. Earlier during the pandemic, it was relatively unusual. Now, more than one in ten confirmed cases has had covid before.
It is definitely an increase in the number of reinfections compared to what we have seen before. The Omicron variant and a too long-time span from the latest dose of vaccine are some of the reasons why more and more people are now getting covid-19 again.
In this year (2022), the proportion of re-infections increased steadily. During the first week , 5.4 percent of all confirmed cases were re-infected cases. During week five, the proportion had increased to 11 percent!
All this make me wonder why I have been taken 3 Covid jabs! But that is enough for me, I will not be forced to take any more.
Hope you all are in good health, Salud!
