Now booming on Moscow’s black market: Fake vaccine certificates

#Russia #COVIDVaccine #COVID19 #coronavirus It took just a few hours for fraudsters to act after Moscow's mayor announced this month that coronavirus vaccinations were compulsory for most of the city's service-sector employees. Accounts advertising the availability of fake coronavirus vaccination certificates suddenly appeared as social media followers of Russians who identified as working at restaurants or bars. A new black market was born with a deep potential clientele: th

US NIH begins study of COVID-19 vaccination during pregnancy and postpartum

#pregnancy #COVID19 #coronavirus #COVIDVaccine #SARSCoV2 Researchers will measure antibodies against SARSCoV2, assess vaccine safety & evaluate transfer of vaccine-induced antibodies to infants A new observational study has begun to evaluate the immune responses generated by COVID-19 vaccines administered to pregnant or postpartum people. Researchers will measure the development and durability of antibodies against SARS-CoV-2, the virus that causes COVID-19, in people vaccina

San Francisco named 2021's best US city for summer vaxcation

#SanFrancisco #vaxcation #vacation #COVID19 #COVIDVaccination #COVIDVaccine #tourism A new survey lists San Francisco as the top when it comes to the best city in the U.S. for those looking for a safe and fun place to visit this summer. With the summer travel season officially here, and with the COVID-19 pandemic still not completely in the rear view mirror, many people are making safety a key factor in their destination decision. The survey by the group LawnStarter rounded u

‘Two Americas’ may emerge as Delta variant spreads and vaccination rates drop

#DeltaVariant #COVID19 #COVIDvaccination #COVIDvaccine #coronavirus #Delta Only 52% of Republicans said they were vaccinated & 29% have no intention of getting a vaccine. 77% of Democrats said they were already vaccinated, & only 5% are resisting the vaccine. With Covid vaccination penetration in the US likely to fall short of Joe Biden’s 70% by Fourth of July target, pandemic analysts are warning that vaccine incentives are losing traction and that “two Americas” may emerge

Don’t Count on Needing a Covid Booster Shot, WHO Scientist Says

#COVID19 #COVIDVaccination #COVIDvaccine #coronavirus As some governments and pharmaceutical officials prepare for Covid booster shots targeting more-infectious virus variants, health authorities say it’s too early to tell if they will be required. “We do not have the information that’s necessary to make the recommendation on whether or not a booster will be needed,” Soumya Swaminathan, the World Health Organization’s chief scientist, said in a Zoom interview Friday. The “sci

Novavax’s coronavirus vaccine is 90 percent effective, study finds

#Novavax #coronavirus #COVID19 #COVIDVaccines #COVIDVaccine #Vaccines The vaccine is one of six the U.S. bet on but is likely to have its biggest impact globally Novavax, a Maryland biotechnology company that endured delays in developing a coronavirus vaccine, revealed results Monday showing that the world is close to having another shot that prevents illness and death, stops virus variants — and proves easy to store. The two-shot regimen was 90 percent effective at preventin

Novavax Offers US a Fourth Strong Covid-19 Vaccine

#Novavax #COVID19 #coronavirus #COVIDVaccines #COVIDVaccine #COVID The company’s large U.S. trial found an efficacy rate of about 90 percent. But at this point, the nation is awash in other shots. Novavax, a small American company buoyed by lavish support from the U.S. government, announced on Monday the results of a clinical trial of its Covid-19 vaccine in the United States and Mexico, finding that its two-shot inoculation provides potent protection against the coronavirus.

The indirect effect of mRNA-based Covid vaccination on unvaccinated household members

#COVID #COVIDvaccine #COVID19 #vaccines Abstract This paper studies the direct and indirect effectiveness of Covid-19 vaccines among vaccinated healthcare workers and their unvaccinated adult household members in a mass vaccine program in Finland. Methods We used national databases that record all polymerase chain reaction (PCR)-confirmed SARS-CoV-2 infections and mRNA-based (BNT162b2 by Pfizer-BioNTech or mRNA-1273 by Moderna) vaccine doses administered in Finland since the

Widespread vaccination of adults helps protect unvaccinated children

#COVIDvaccine #COVID19 #COVID #coronavirus The study, based on anonymized Israeli medical records, showed that vaccination's benefits extend to people who have not received a shot. New data from Israel, which had the fastest Covid-19 vaccine rollout in the world, provides real-world evidence that widespread vaccination against the coronavirus can also protect people who are unvaccinated. The Israeli study, which was published in the journal Nature Medicine on Thursday, took a

We’ll Probably Need Booster Shots for Covid-19. But When? And Which Ones?

#COVID19 #coronavirus #vaccines #COVIDVaccine Although many scientists estimate that the COVID19 vaccines authorized in the US will last at least a year, no one knows for sure. It’s also unclear whether emerging variants of the coronavirus will change our vaccination needs. As the nation edges closer to President Biden’s goal of a 70 percent vaccination rate, many people are beginning to wonder how long their protection will last. For now, scientists are asking a lot of quest

WHO approval of Chinese CoronaVac COVID vaccine will be crucial to curbing pandemic

#COVID19 #coronavirus #CoronaVac #COVIDvaccine #China WHO approved a 2nd Chinese vaccine for emergency use. CoronaVac was 51% effective at preventing COVID19 in late-stage trials. Overall protection is lower than for other vaccines already approved. But it is 100% effective at preventing severe disease & death. CoronaVac is one of two Chinese vaccines already sustaining vaccination campaigns in more than 70 nations. Both should soon be much more widely available to low-income

As COVID19 Vaccines Turn Pandemic’s Tide, US & Europe Diverge on Path Forward.

#COVID19 #COVIDvaccine #corinavirus #pandemic The US has lifted most rules for those who are vaccinated against Covid-19, but a new coronavirus variant is leading Britain & the EU to move with more caution. The split is particularly stark in Britain, which is facing the spread of a new variant, while America has essentially lifted all rules for people who are vaccinated. Over Memorial Day weekend, 135,000 people jammed the oval at the Indianapolis 500. Restaurants across the

Africa is not ready for imminent third coronavirus wave, says WHO

#COVID19 #COVID #coronavirus #Africa #COVIDvaccine With vaccine deliveries at a near-standstill and lacking key resources in frontline care, Africa is poorly prepared for the third wave of the coronavirus pandemic, the UN warned on Thursday.

After COVID-19 successes, researchers push to develop mRNA vaccines for other diseases

#mRNA #COVID19 #coronavirus #vaccines #COVIDvaccine #cancer mRNA vaccines are now in the limelight as a key tool for tackling COVID-19, but the technology was originally developed for other diseases, such as cancer, that researchers are now hoping to treat. When the broad range of vaccines against COVID-19 were being tested in clinical trials, only a few experts expected the unproven technology of mRNA to be the star. Within 10 months, mRNA vaccines were both the first to be

Vaccines that can protect against many coronaviruses could prevent another pandemic

#COVID19 #coronavirus #SARSCoV2 #COVIDvaccine In 2017, three leading vaccine researchers submitted a grant application with an ambitious goal. At the time, no one had proved a vaccine could stop even a single beta coronavirus—the notorious viral group then known to include the lethal agents of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), as well as several causes of the common cold and many bat viruses. But these researchers wanted to
