A short 🧵on a recent study by @MaggieLind2 with @MHitchingsEpi@datcummings Albert Ko et al. Data show that immunity induced by vaccines, prior infection or both (hybrid) protects against SARS-CoV-2 infection when viral exposure is low to moderate (1/)

Unfortunately, the ants are pulling off the paint we're using. Any recommendations for brands/types of paint that work better? This is enamel model paint.

Mesmo quem teve covid deve se vacinar. Essa é uma das evidências mais robustas e generalizáveis que dá suporte a isso, resultado de uma colaboração entre muitos pesquisadores e pesquisadoras e instituições. Ainda em revisão.
Vacine-se
Em uma colaboração entre os grupos VEBRA e VIGIVAC, nós fizemos um estudo caso-controle do tipo teste-negativo no Brasil. Selecionamos indivíduos confirmados por PCR ou Antigeno, adultos, e avaliamos a efetividade das 4 vacinas usadas no Brasil.
Vale a pena ler os métodos,
Já tive COVID, devo me vacinar?
Sim, sem dúvida. Como já dizíamos, agora com dados. Mostramos (preprint) que o ganho em proteção é muito grande. Para hospitalizações/óbito, após 2a dose:
➡️ 89.7% Pfizer
➡️ 89.9% AstraZeneca
➡️ 81.3% CoronaVac
Vacine-se

New research by @UF_CLAS and EPI biologist @datcummings shows that as populations of people gain immunity to dengue, it drives evolutionary pressures that select for viral evolution—and newly susceptible hosts. bit.ly/3HAZUZG@UFNews@UFExplore
May reflect evasion of heterotypic immunity but lots of work to do to understand selective pressures that could give rise to this pattern. With @hsalje Steve Whitehead @wrair Ana Coello @HuangAngkanaT@ufidd and others. 2/2
New work led by @LeahKatzelnick characterizing antigenic evolution of dengue viruses over 20 years in Thailand science.org/doi/10.1126/sc… We found that dengue viruses became more antigenically distant from each other over time. 1/2
Today we hit 750,000 Americans lost to COVID19. We’re on trajectory to hit 800,0000 by year’s end. Those last 100,000+ maybe even 200,000 died unnecessarily because vaccines were widely available. They chose not to get vaccinated, sometimes even defiant. They died by antiscience
Vaccination with CoronaVac was associated with a reduction in symptomatic covid-19, hospital admissions, and deaths in adults aged ≥70 years, finds new research.
Vaccine protection was low until completion of the two dose regimen: ow.ly/HQzs50FV2XQ
At this point, you are either vaccinated or you are going to catch Delta.
And whether you are young adult or old, when you catch Delta unvaccinated, you will have the highest chance of being hospitalized compared to almost any disease you have caught in your life.
Our work about individual NPI policies’ effects on COVID-19 spread in the US counties is now out @NatureComms. We found, earlier in the pandemic, multiple interventions were needed to bring Rt below 1. Relaxing some NPIs needs counterbalanced by others.1/3 nature.com/articles/s4146…
In my latest @TheAtlantic, I reflect on the year of the racial pandemic within the viral one. In sum: People of color were infected, hospitalized, impoverished, and killed at the highest rates, while receiving the fewest medical + economic protections. 1/4
