The coronavirus conundrum - Reinfections by COVID-19, long COVID - Bivalent vaccines - The pregnant woman - Human rights & Ethics

ABSTRACT

At the end of the second year of the COVID-19 pandemic, it seems that the enigmatic coronavirus is giving us some respite. However, the number of people infected has started to rise in the northern hemisphere, where a strong winter with snowfall is approaching. But this new increase is also observed in the southern hemisphere, as in Peru, when we are in spring. SARS-CoV-2 continues to differentiate into a multitude of variants and subvariants, some of which are more easily able to evade human immunity and that achieved with mRNA vaccines, and also may not respond to monoclonal antibody treatments. Current clinical information is oriented to the expectation that existing vaccines could at least reduce hospitalizations, intensive care admission and deaths. Learning about the clinical effects of SARS-CoV-2 infection, the occurrence of reinfection, and long-term physical and mental harm continues, with prevention of infection, reinfection, and prolonged COVID being sought.
