Antibodies play a key role in the fight against viruses

In my country in recent weeks there has been a significant increase in the number of cases of virus infections, despite the fact that millions of people have already received the vaccine, which suggests that the immune system is not responding adequately to the virus.

In this regard, I should mention that a few days ago I read an article where it was mentioned that T-cell vaccines could be the key to long-term immunity, an element that would undoubtedly counteract the significant increase in the number of cases of virus infections.

Another element to consider in recent virus infections is that since variant has rapidly increased virus infections, the focus is once again on antibodies, and it is with good reason that some countries have mounted booster vaccination campaigns in response to recent virus.

Scientists have questioned whether permanently recharging antibodies by applying doses of already available vaccines, only to see them soon diminish, is a sustainable strategy.

This makes sense, considering that when the body is infected, say with a virus, it responds by producing white blood cells called lymphocytes. The main types of lymphocytes are B cells, which produce antibodies, and T cells, which support the production of B cell antibodies or act as killer cells to destroy the virus.
