CDC scientist says knowledge is proscribed to judge shot for normal inhabitants

A CDC scientist said Monday that the data needed to properly evaluate Covid-19 vaccine booster vaccinations for the general population is limited – even if President Joe Biden pressures health officials to delete the vaccinations widespread use early in the week from September 20th.

The presentation by Dr. Sara Oliver at a meeting of the Centers for Disease Control and Prevention Advisory Group suggests the panel may limit its initial endorsement of additional shots to vulnerable groups and healthcare workers.

Several studies suggest that the approved Covid vaccines may still be effective in preventing serious illness and hospitalization, but may be less effective in preventing infections or mild symptomatic illnesses, according to Oliver. The CDCs The Advisory Committee on Vaccination Practices meets on Monday Consider booster vaccinations for all eligible Americans. The panel is also due to vote on the final approval of the Pfizer vaccine by the Food and Drug Administration.

Since the highly contagious Delta variant first appeared, the vaccine’s effectiveness ranged from 39% to 84%, according to Oliver’s presentation, which referred to several separate studies. A study that looked at health care workers and first responders showed that the vaccine’s overall effectiveness dropped to about 65% in July – up from about 90% in February. Israel dates show Pfizer’s vaccine effectiveness has dropped to just 39% in that country.

Scientists have said that the vaccines become less effective over time, and the Delta variant is a more resilient strain that is able to break through that protection.

According to Oliver’s presentation slides, “it is important to monitor efficacy trends by disease severity over time”.

It was pointed out on the slides that vaccines often require multiple doses. Hepatitis B and HPV vaccinations, for example, require a third dose after six months.

“Vaccines that require more than one dose don’t necessarily mean that an annual booster is required,” Oliver said during the presentation.

Once booster shots are available, nursing home residents, health care providers, and the elderly – the first groups to be vaccinated in December and January – will likely be given priority for the additional vaccinations, according to the CDC slides.

The CDC stressed that vaccinating the unvaccinated should be a “top priority” and giving booster doses to vaccinated individuals should not deter those who remain unprotected from the virus.

The agency also emphasized the importance of vaccine availability around the world.

“An uncontrolled global spread that could lead to new variants threatens the control of the pandemic everywhere,” said Oliver. In addition to global distribution, policy on boosters “should also consider equity in the US population,” she added.

Monday’s meeting comes after President Joe Biden said Friday US regulators are considering giving Covid booster vaccinations five months after completing the primary series and bringing forward the expected schedule for a third vaccination by three months.

Scientists have sharply criticized The Biden government’s urge to distribute booster syringes widely says the data provided by federal health officials are not compelling enough to currently recommend third vaccinations for most of the American population.

The Biden government has publicly stated that the third dose will not be given without FDA approval and a vote from ACIP.

WHO scientist warns world is at ‘very dangerous’ stage as Covid instances rise

The world must step up its efforts to fight Covid-19 – and countries must not give up their vigilance, the chief scientist of the World Health Organization warned on Monday as Coronavirus Cases are increasing around the world.

“We are in a very risky phase,” said Dr. Soumya Swaminathan from the World Health Organization. “We have to double up, this is not the time to slack off.”

The WHO warned about this last week After six consecutive weeks of declines, new Covid-19 cases increased worldwide. More than 2.6 million new cases were reported in the last week of February, a 7% increase from the previous week, according to the health department.

The Eastern Mediterranean, Southeast Asia, Europe and America all recorded increases of between 6% and 14%.

Although vaccines are on the rise for us in the nation, we cannot give up our vigilance.

“This is partly due to lockdown fatigue, you know. It’s because people … maybe loosen up believing vaccines are on the way,” Swaminathan told CNBC “Squawk Box Asia” On Monday. New variants could also play a role, she added.

“We have to … do everything we know to keep these viruses under control, keep transmission under control until we have enough vaccines,” she said, warning health systems could become overloaded again.

“Health workers around the world are exhausted, they have been battling it for over a year now,” she added.

Other health professionals have also suggested that it is not time to get complacent.

Julie Morita, executive vice president of the Robert Wood Johnson Foundation, said it was important to realize that infections, hospitalizations and deaths are still high even after falling from their peaks in the US

“There is still a need for us to wear our masks, social distance, avoid large crowds while we are being vaccinated,” she told CNBC “Street Signs Asia” On Monday.

“Although vaccines are on the rise for us in the nation, we cannot give up our vigilance,” she said. “It’s way too early to relax.”
