Will the COVID-19 vaccines encourage the emergence of new variants or immune evasion?

Biology/Immunity COVID Variants Vaccines

A: No. Vaccines REDUCE opportunities for viral replication needed for variants to emerge. ➡️ TL;DR: The virus has more opportunity to replicate in unvaccinated populations, creating a FAR bigger risk for the development of SARS-CoV-2 mutations. Even so, the good news is that the emergence of variants that fully evade vaccine induced immunity is considered

How does natural immunity to SARS-CoV-2 infection differ from immunity generated by COVID-19 vaccines?

Biology/Immunity Vaccines

A. COVID-19 vaccines induce higher levels and a broader range of neutralizing antibodies to the receptor binding domain (RBD) of the spike protein than does natural infection. Vaccine-induced antibodies are less likely to be affected by changes in the RBD seen in the current SARS-CoV-2 variants, and are therefore more likely to be more effective

¿Qué es la terapia genética?

Biology/Immunity Posts en Español Vaccines

P: ÂżQuĂ© es la terapia genĂ©tica ? ÂżEn quĂ© se diferencia de las vacunas? R: Las terapias genĂ©ticas tratan enfermedades utilizando herramientas genĂ©ticas. Las vacunas no cambian su ADN. Por lo general, las terapias genĂ©ticas funcionan al realizar cambios duraderos en su ADN – el “libro de recetas” genĂ©tico que prevea las instrucciones para crearlo

Why might Delta be more transmissible?

Biology/Immunity COVID Variants

A: In the words of virologist Dr. Angela Rasmussen, “people infected with Delta are shedding a s**t-ton more virus than with earlier variants.” A newly released study has provided some clues to Delta’s transmissibility tricks by testing viral loads in quarantined close contacts of confirmed cases. Contacts were tested daily by PCR, and the course
