In my country in recent weeks there has been a significant increase in the number of cases of Covid-19 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 Covid-19 infections.
Another element to consider in recent coronavirus infections is that since the Omicron variant has rapidly increased Covid-19 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 Covid-19 surges.
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.
