A real-world study finds that approved vaccines are highly effective as drugmakers work to expand access
Earlier this week, the Centers for Disease Control published results from a study that found that the Pfizer-BioNTech and Moderna vaccines appear 90 percent effective at protecting against Covid-19 in the real world. The data is yet another promising indicator that these vaccines work really well, but, importantly, this doesn’t mean that they offer complete protection—masking and distancing in public are important even if you’ve received both shots. As the last year has made eminently clear, our understanding of this disease, and how to fend it off, is constantly evolving, so it’s important for everyone to continue taking all the precautions that we know to be effective.
Meanwhile, the drug companies are working to expand approval and distribution. Pfizer announced this week that its vaccine appears to be safe and effective in teens as young as 12, while Johnson & Johnson kicked off its own trial for people ages 12 to 17. And on Thursday, the Food and Drug Administration announced that it will let Moderna put up to 50 percent more doses in each vial in an amendment to its emergency use authorization. The change is expected to speed up distribution.
The CDC says that fully vaccinated people can travel if they take other pandemic precautions
This morning the CDC issued new travel guidelines for people who have been fully vaccinated, saying that it’s low-risk for them to travel domestically and internationally, though they should continue to take other precautions like wearing a mask and abiding by social distancing guidelines. The potential return to activities like air travel has sparked questions about how people will prove they’ve been vaccinated. There’s been talk of “vaccine passports,” and many plans to create them are underway, but doing so in a way that’s ethical and equitable, and protects people’s privacy, may be a challenge.
This latest update from the CDC comes just a few days after its director warned Americans not to ease Covid-19 restrictions just yet. Many Americans are giddy at the thought of a semi “normal” summer, but until vaccines are widespread, this virus will continue to evolve and spread.
Cases rise worldwide, with some countries instituting new lockdowns while others resist taking precautions
In recent days, countries around the world including Turkey and Bangladesh have logged their highest daily case counts yet. The situation in Brazil continues to be particularly dire. São Paolo, its largest city, recorded record daily burials this week, with cemeteries staying open until 10 pm and gravediggers exhuming old graves to make room for new deaths from Covid-19. Even so, President Jair Bolsonaro still refuses to impose a lockdown or any other stringent measures that could curb the virus’ spread.
Cases also continue to rise in Europe, a situation for which the World Health Organization says the region’s “unacceptably slow” vaccination efforts are to blame. Right now 27 European countries are in partial or full lockdown, including France, which will extend its measures to encompass the whole country for four weeks starting on Saturday.
