WASHINGTON, United States — Pfizer and BioNTech said Monday their Covid-19 vaccine remained 100 percent effective in children 12 to 15 years old, four months after the second dose.

The companies said that the new data, which involved 2,228 trial participants, will help support their applications for full approval in the United States and worldwide.

No serious safety concerns were observed in individuals with at least six months of follow-up after the second dose.

"As the global health community works to increase the number of vaccinated people around the world, these additional data provide further confidence in our vaccine's safety and effectiveness profile in adolescents," said Pfizer CEO Albert Bourla in a statement.

"This is especially important as we see rates of COVID-19 climbing in this age group in some regions, while vaccine uptake has slowed. We look forward to sharing these data with the FDA and other regulators."

The vaccine was granted "emergency use authorization" for adolescents by the US in May and the companies plan to soon seek full approval. The vaccine is currently only fully approved in people aged 16 and older.

Among the 2,228 participants, there were 30 confirmed symptomatic Covid cases without evidence of prior infection, all in the placebo group.

This corresponds to a vaccine efficacy of 100 percent. Efficacy was consistently high across gender, race, obesity levels and comorbidity status.

The main safety concern among this age group is vaccine-linked myocarditis (heart inflammation) in males.

But such cases are very rare, and the benefits of vaccination continue to strongly outweigh the risks, data has shown. Covid itself can cause myocarditis, both more often and a more severe form.

Chile on Thursday announces it would start vaccinating children aged three and up against the coronavirus, after successfully innoculating around 90 percent of its initial target population.

Children under the new rollout will receive the Chinese CoronaVac shot already used for kids aged six to 15, the Public Health Institute says. 

For 16 to 18-year-olds, Chile uses the Pfizer/BioNTech vaccine. — AFP

COVID-19 vaccines reduce transmission of the dominant Delta variant by about 40%, the WHO says, warning that people were falling into a false sense of security concerning jabs.

The World Health Organization's director-general Tedros Adhanom Ghebreyesus says many vaccinated people were wrongly thinking the jab meant they no longer needed to take any other precautions.

Fully-immunized people must stick with measures to avoid catching the virus and passing it on, Tedros insists, spelling out how the more contagious Delta meant the vaccines were not as effective against transmission. — AFP

Canada begins mmunizing children aged 5-11 against COVID-19, joining a handful of nations including Israel and the United States in offering shots to this age group.

At Montreal's convention center, a few dozen youngsters were among the first to receive the Pfizer doses authorized since last Friday for this age group.

To help ease their fears of needles, additional measures have been taken such posting stickers of unicorns or hockey players on partitions between nursing stations, longer appointments than for adults, and a dog to pet. — AFP

Leading Russian doctors on Wednesday invited celebrities and politicians with anti-vaccine views to visit COVID red zones in hospitals and see for themselves the effects of the pandemic.

In an open letter published by state news agency TASS, 11 doctors from several cities wrote to a dozen public figures who expressed anti-vaccine views to hundreds of thousands of followers on social media.

Russia, one of the countries worst-hit by the coronavirus pandemic, is struggling with widespread opposition to vaccination even though it has developed several homegrown jabs including Sputnik V.

Despite multiple pleas from President Vladimir Putin, only 37% of Russians are fully vaccinated and the country has seen more than 1,000 deaths a day in recent weeks.

In their letter, the doctors told several singers, actors, TV personalities and politicians who had expressed skepticism over vaccinations that they would take the time to show them around COVID treatment centers. — AFP
