I fully support the use of vaccines, but I worry about possible long-term side effects with the new vaccines. How can anyone say with any confidence there will be no long-term consequences with vaccines that have been developed so rapidly.
Well because what it does in your body is very logical and basically the same as with traditional vaccines: your body produces antibodies, stores info in memory B cells and destroys the mRNA. The mRNA is then gone within hours so it can’t cause any effect in the future. The only effects that it will cause will be few hours after the shot. After that it‘s just gone.
Antibodies and memory B cells are created upon detecting the newly created (and later destroyed) spike proteins just the same way as in a traditional vaccine, so there‘s no added risk there. We know exactly how the antibodies and memory cells behave since they are created in the same fashion as always. Just a reaction to new unknown spike proteins.
Vaccination is an easy safe and effective way to protect against an infectious disease before it comes into contact with an infected person. About 20 diseases such as polio diphtheria pertussis tetanus and measles can be prevented by vaccination when we get vaccinated we protect not only ourselves but also the people around us. Some people are advised not to take certain vaccines in which case those who receive the vaccine help prevent the spread of the disease.
