Desde o início da PANDEMIA do vírus infecioso e mortal SARS CoV-2, tendo-se colocado por associação e por alguma semelhança a questão de se este vírus seria ou não periódico,

A new study of the U.K. and South Africa variants of SARS-CoV-2 predicts that current vaccines and certain monoclonal antibodies may be less effective at neutralizing these variants and that the new variants raise the specter that reinfections could be more likely.

─ Tal como sucede com o vírus INFLUENZA (GRIPE), regressando todos os anos (crónico) e obrigando a uma atualização da VACINA ─

The company (of Novavax vacine) reported on Jan. 28 that the vaccine was nearly 90% effective in the company's U.K. trial, but only 49.4% effective in its South Africa trial, where most cases of COVID-19 are caused by the B.1.351 variant.

Confirmando-se cada vez mais a ainda hipótese da cronicidade da doença COVID-19, regressando tal como na GRIPE periodicamente ainda-por-cima com novas estirpes/VARIANTES:

"Our study and the new clinical trial data show that the virus is traveling in a direction that is causing it to escape from our current vaccines and therapies that are directed against the viral spike."

E se neste curto espaço de tempo de 1 ano se conseguiu colocar no terreno uma VACINA para combater e vencer o VÍRUS ORIGINAL,

"If the rampant spread of the virus continues and more critical mutations accumulate, then we may be condemned to chasing after the evolving SARS-CoV-2 continually, as we have long done for influenza virus. Such considerations require that we stop virus transmission as quickly as is feasible, by redoubling our mitigation measures and by expediting vaccine rollout."

Esta (vacina) poderá ter um tempo de vida algo reduzida com a chegada de novas VARIANTES, como as da GB (já em circulação), as da África do Sul (a começar a disseminar-se) e as do Brasil (aí a chegar),

"The concern here is that reinfection might be more likely if one is confronted with these variants, particularly the South Africa one."

─ Como se estivéssemos em 2021, a tomar a vacina indicada para 2020.
