A study from JAMA Network Open shows the level of protection from a previous bout of symptomatic COVID is the same as that from vaccines, and the window of immunity is longer than with vaccines. The study from JAMA Network Open looked at 100,000 unvaccinated patients of a large health care system who were tested for COVID between October 2020 and November 2021. A COVID infection was 85% protective against reinfection and 88% protective against hospitalization. The defense lasted up to nine months, which was as far out as the study went. The study occurred before the Omicron wave. “The results provide new insight into the length of protection following an initial infection among the unvaccinated population,” says Dr. Amy Compton-Phillips in an article from News Medical, “and could have important implications for vaccination guidelines and public health policy.”
Booster Guidance Challenges
The independent vaccine advisory panel to the CDC met to discuss guidance on COVID boosters. Members of the committee expressed some frustration over the lack of clarity about the goals of boosters. Data presented at the meeting showed that two shots plus a booster held up and that the benefit of a fourth shot was only modest. There were concerns about “booster fatigue.” It’s possible a new vaccine will come about that protects against all existing variants, that lasts a year, or combines flu immunization.

What You Eat vs. When You Eat
The same amount of calories in an eight-hour window did not help with weight loss. In a year long study, 139 obese adults in China were given a diet of 1,500 to 1,800 calories a day; half the group ate only between 8:00 a.m. and 4:00 p.m. Nearly all the participants followed their diets, with 97% at six months, and 85% at the 12-month mark. Both groups lost the same amount of weight. Other measures, such as body fat, body mass index, blood pressure, pulse, cholesterol, and blood sugar, also improved, but were no different. The researchers concluded the calorie restriction, rather than the time of day, was the more important factor. However, since both approaches worked, a time-restricted regimen is an alternative option for weight management. More in MedPage Today.
