Pfizer-BioNTech’s COVID-19 vaccine is notably less effective six months after the second dose is administered, a new study finds. Researchers from King’s College London in the UK analyzed COVID-19 testing data and found the vaccine’s effectiveness falls from 88 percent to 77 percent after five to six months. They could not determine whether the lower effectiveness caused an increase in hospitalizations or deaths. The findings could spell trouble in the U.S., where more than 100 million people have received at least one dose of the vaccine – especially as the Indian ‘Delta’ variant continues to spread, causing cases to surge. Federal officials hope that plans to administer boosters in September – pending approval from the U.S. Food and Drug Administration (FDA) will help shore up protection. The British study, published last week, included 1.2 million participants who had received either the Pfizer or AstraZeneca vaccines. While not available for emergency use in the U.S., the AstraZeneca vaccine is widely used across Europe. More than 400,000 participants in the study had been vaccinated with the Pfizer vaccine by July 3. Britain was hit by a third wave of infections during this period after the more infectious Delta variant sparked outbreaks across the country. ZOE, a health data science company that contributed to the study, built an app that would ask users to report daily on whether they are unwell, their symptoms and if they have tested positive for the virus. Using data gathered from the app and Covid testing, researchers determined that a month after vaccination, the vaccine was 88 percent effective. That figure falls to 74 percent after five to six months. NB: Research show the vaccine effectiveness after 8 months falls to 30 to 40 percent. Antivaccers are going crazy. Hello we all new from the start that the vaccines wears off and new variants pop up. No one is jumping off a bridge because the Flu vaccine requires a yearly jab.
