One COVID-19 vaccine in development may be ready for review in December.
Managers at Novavax say they are now enrolling volunteers for a second phase of clinical trials. The data should be ready for assessment within a few months.
Phase 1 data showed the two-dose vaccine in healthy adults producing antibodies in all participants. Tears and pain were the most common local symptoms.
Once the first COVID-19 vaccines are approved, we will not know much about their safety.
‘We will learn as we go along. There are several case studies in our experience where, when faxes were rolled out, we were fairly confident with the safety profile, but that is evolving, “said Dr. Jon Andrus, assistant professor at the Milken Institute School of Public Health of George Washington University.
“I think these vaccines will be safe in the sense that they will not cause serious or permanent adverse events if tested in 10,000, 15,000, 20,000 people,” said Drs. Paul A. Offit with the Children’s Hospital of Philadelphia. “Hopefully that will also be true at post approval when it is tested and seen in 20 million, 30 million people.”
Based on other vaccine histories, a COVID-19 vaccine is likely to produce some sort of adverse reaction. It may be small typical problems with injection than something more serious.
Back in the fifties, the most massive polio vaccination program was stopped because it paralyzed some children and killed a handful.
In the 1970s, the swine flu vaccine caused a very small amount of rare neurological cases. There are other problems such as an allergic reaction or attack.
However, experts say vaccines are one of the biggest advances in modern medicine in preventing unnecessary deaths.
“There is no better cost-effective intervention that medical science has to offer with the exception of safe water and sanitation, so if you look at our life expectancy, vaccines have been incredibly important,” Andrus said.
The Vaccine Injury Litigation Clinic treats cases of vaccine-related injuries and deaths. On average, just over 600 people a year receive benefits from the National Fax Injury Compensation Program. But they admit that faxing injuries are still rare compared to the total numbers of administration faxes each year.
The Centers for Disease Control and Prevention (CDC) says for every 1 million doses of vaccine distributed, one person was compensated.
