The efficacy of the vaccine after the first dose is about 52 percent, according to Dr. William C. Gruber, senior vice president of Pfizer Vaccine Clinical Research and Development. After the second dose, that rises to about 95 percent. “Two doses of vaccine provide maximum protection,” he said.
Many experts have expressed concern that the coronavirus vaccines might protect some people better than others. But the results in the briefing materials indicate no such problem. The vaccine has a high efficacy rate in both men and women, as well as similar rates in white, Black and Latino people. It also worked well in obese people, who carry a greater risk of getting sick with Covid-19.
Some vaccines for other diseases set off a weak immune response in older adults. But Pfizer and BioNTech found that people over 65 got about as much protection from the coronavirus vaccine as younger people did.
Even if the vaccine is authorized by the F.D.A., the trial will continue. In the briefing documents, the companies said that they would encourage people to stay in the trial as long as possible, not knowing whether they got the vaccine or the placebo, so that the researchers could continue to collect information about whether the vaccine was safe and effective….
The new Pfizer analysis revealed that many volunteers who received the vaccine felt ill in the hours after the second dose, suggesting that many people might have to request a day off work or be prepared to rest until the symptoms subside. Among those between ages 16 and 55, more than half developed fatigue, and more than half also reported headaches. Just over one-third felt chills, and 37 percent felt muscle pain. About half of those over age 55 felt fatigued, one-third developed a headache and about one-quarter felt chills, while 29 percent experienced muscle pain.
“Taking a day off after the second dose is a good thing to anticipate,” Dr. Iwasaki said.
