US coronavirus: enough people need to take vaccine for it to work, says Fauci


“It’s a combination of how effective a vaccine is and how many people are using it,” Fauci said. “If you have a very effective vaccine and too few people get vaccinated, you are not going to realize the full important effect of having a vaccine.”

The less protective a vaccine, the more people need to get it to ensure population-wide immunity, Fauci said. The fundamental goal is to lower the level of infection so low that when there are few outbreaks they are easy to control, he said.

A recent Kaiser Family Foundation poll found that 54% of those polled said they would not receive the vaccine if it was available for free before the November 3 presidential election – a deadline suggested by President Trump, but according to health officials, it is unlikely.

The reluctance of many people to get a Covid-19 vaccine when it becomes available is an issue that needs to be addressed urgently, said Dr Francis Collins, director of the National Institutes of Health.

“Those who are reluctant to get vaccinated have seen their reluctance reinforced by a variety of things that are happening right now, especially the unfortunate mix of science and politics,” Collins said at an event hosted by the National Academies of Sciences , engineering and medicine. “I don’t want us to have a conversation a year from now about how we have the solution to the worst pandemic in over 100 years in our hands, but we haven’t been able to convince people to take responsibility for that, ”Collins said.

Fauci said he still believes it will be the last months of the year before a vaccine is proven to be safe and effective. “I would always put my money in November / December,” Fauci said during a Congressional Hispanic Caucus Institute panel on Global Pandemics.

Rich countries have captured most of the vaccine supply

Rich countries such as the United States, Britain and Japan have bought more than half of the planned supply of the coronavirus vaccine, the international anti-poverty nonprofit said on Wednesday. Oxfam.

These countries represent 13% of the world’s population, but have purchased future supplies of 51% of coronavirus vaccines, Oxfam said.

The group used data collected by analytics firm Airfinity to analyze published agreements between governments and vaccine makers. Oxfam has calculated that five organizations – AstraZeneca, Gamaleya in Russia, Moderna, Pfizer and Sinovac in China – have the combined production capacity to produce 5.94 billion doses. That’s enough to cover 2.97 billion people – less than half of the world’s population, if everyone needs two doses, as seems likely.

“Supply agreements have already been concluded for 5.303 billion doses, of which 2.728 billion (51%) have been purchased by developed countries, including the United Kingdom, the United States, Australia, Hong Kong and Macao , Japan, Switzerland and Israel, as well as European countries. Union, ”Oxfam said in a statement.

The rest has been bought or pledged to developing countries including India, Bangladesh, China, Brazil, Indonesia and Mexico, he added.

“Access to a vaccine that saves lives shouldn’t depend on where you live or your money,” said Robert Silverman of Oxfam. “The development and approval of a safe and effective vaccine is crucial, but it is just as important to ensure that vaccines are available and affordable for everyone. COVID-19 anywhere is COVID-19 everywhere. ”

Oxfam noted that AstraZeneca has pledged two-thirds of the doses it produces to developing countries.

Seven deaths from coronavirus linked to marriage

A marriage in Maine is linked to 176 cases of Covid-19 and the deaths of seven people who did not attend the celebration, highlighting how easily and quickly the coronavirus can spread during social gatherings, experts say in public health.

For months, doctors have emphasized the importance of wearing masks, social distancing and avoiding large gatherings.

But epidemics are due to the events of Memorial Day, the 4th of July celebrations and a huge rally of motorcycles in Sturgis, South Dakota.

The wedding in Millinocket on Aug. 7 had about 65 guests, a violation of the state’s 50-person limit for indoor events, the Maine Center for Disease Control and Prevention said.

The event is linked to outbreaks that took place in a nursing home and prison, both located over 160 km from the wedding venue, among people who had only secondary or tertiary contact with a participant.

Residents of the Maplecrest Rehabilitation and Living Center accounted for 39 marriage-related cases and six of the seven deaths to date, said Maine CDC director Dr. Nirav D. Shah.

“The virus favors gatherings,” Shah added. “He doesn’t distinguish between happy events like a wedding celebration or a sad farewell like a funeral. “
