Pfizer says effectiveness of COVID-19 vaccine weakens over time

Pfizer said data from Israel and the United States show that its COVID-19 vaccine efficacy declines over time and claimed booster doses are effective in tackling new virus variants.

Federal health officials announced a September 20 target date for trying and rolling out booster shots to the general public two weeks ago, though a recent study by several top scientists at the World Health Organization and the Food and Drug Administration (FDA) found that the general public does not need a booster dose.

Pfizer said during its presentation this week, “Real-world data from Israel and the United States show that success infection rates are rising faster than those who have been vaccinated earlier in vaccination campaigns.” ” Posted on the FDA website.

And evidence from studies indicates that “the decrease in vaccine effectiveness against COVID-19 infections is primarily due to a lack of vaccine immune responses over time as a result of the delta variant escaping vaccine protection,” Pfizer said.

Based on its data, Pfizer said a booster dose should be given to everyone 16 years of age and older six months after receiving a second dose of mRNA vaccine.

The pharmaceutical giant, which has partnered with BioNTech for its vaccine, cited a study by healthcare giant Kaiser Permanente that suggested getting a second dose after five months could reduce the risk of COVID-19 infection in the first month. Security dropped from 88 percent to 47 percent.

The company is attempting to make an argument ahead of an important FDA meeting scheduled for Friday, where a panel is set to debate and vote on whether to recommend booster shots or a third dose.

But in a study published Monday by The Lancet, two senior FDA vaccine reviewers who are expected to leave the agency soon and more than a dozen top researchers argued that booster shots are not needed for the general population. They argued that the potential side effects from the additional dosage could outweigh the benefits, arguing that such an event would actually increase vaccine hesitancy.

The study, published in the Lancet, said, “The current evidence does not … indicate a need for growth in the general population, in which efficacy against severe disease remains high.” The authors wrote, “Even if boosting was ultimately shown to reduce the medium-term risk of severe disease, the current vaccine supply could save more lives than if used in a previously unvaccinated population.” She goes.”

Meanwhile, WHO Director-General Tedros Adhanom Ghebreyesus issued a scathing statement earlier this month calling on wealthy countries, including the United States, to put a moratorium on booster shots by the end of this year. Because companies are ramping up production of additional vaccine doses, it deprives poor countries of early vaccines, he argued at a news conference.

“I will not be silent when the companies and countries that control the global supply of vaccines think that the world’s poor should be satisfied with leftovers,” he said at a news conference on 8 September. “Because manufacturers have preferred or are legally obliged to fulfill bilateral deals with rich countries willing to pay top dollar, low-income countries have been denied the tools to protect their people. “

COVID-19 is a disease caused by the CCP (Communist Party of China) virus.
