If you’re not following the COVID news out of Brazil and are under the impression that cases must be down there since they’re down everywhere, let me shatter your illusion. Not only are things bad, they’re worse than they’ve ever been:
(Graph)
Six days ago Brazil recorded 1,840 deaths in a single day, its worst of the pandemic. Its seven-day daily average of deaths stands at 1,540, also its worst since COVID arrived. Why are cases exploding there when they’re receding in most of the rest of the world? Reporters have been wrestling with that question lately but one prime suspect is the rise of the P.1 variant inside the country, which has proved itself capable of reinfecting people who have already contracted and recovered from common COVID. P.1 has already reached the U.S. too: A case of it was detected recently in Oregon. Needless to say, a strain capable of overcoming natural immunity is a severe threat to herd immunity, potentially putting the U.S. back at square one in defeating COVID until a vaccine can be developed and distributed that’s able to defeat the Brazilian variant.

Results from a new study suggest that that vaccine already exists, though. If you’ve gotten the Pfizer shots, you should be safe.

Exclusive: Oxford study indicates AstraZeneca effective against Brazil variant, source says

RIO DE JANEIRO (Reuters) - Preliminary data from a study conducted at the University of Oxford indicates that the COVID-19 vaccine developed by AstraZeneca PLC is effective against the P1, or Brazilian, variant, a source with knowledge of the study told Reuters on Friday.

The data indicates that the vaccine will not need to be modified in order to protect against the variant, which is believed to have originated in the Amazonian city of Manaus, said the source, who requested anonymity as the results have not yet been made public.

Early results indicated the AstraZeneca vaccine was significantly less effective against the South African variant, which is similar to P1. South Africa subsequently paused the use of the vaccine in the country.

The information comes as a plasma study published ahead of peer review on Monday (https://bit.ly/3bX3LBa) suggested the CoronaVac COVID-19 vaccine developed by China's Sinovac Biotech may not work effectively against the Brazilian variant.

As one of the articles pointed out, by the various vaccines targeting the SARS-CoV-2 spoke, by which it invades cells, the number of characteristics that can change by mutation without the virus ceasing to have an invasion mechanism is very limited. So far I have not seen any information about Moderna's effectiveness against this Brazil variant. OTOH, J & J's vaccine was tested, among other places, in Brazil and appears to be effective against the Brazil variant.

Sinovac Biotech's vaccine does not target the spike, but uses traditional dead/weakened virus technology.
