Immunity to the coronavirus lasts at least a year, probably much longer, and improves over time especially after vaccination, according to two new studies. The findings may help put to rest lingering fears that protection against the virus will be short-lived.
Together, the studies suggest that most people who have recovered from COVID-19 and who were later immunized will not need boosters. Vaccinated people who were never infected most likely will need the shots, however, as will a minority who were infected but did not produce a robust immune response.
Both reports looked at people who had been exposed to the coronavirus about a year earlier. Cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed, according to one of the studies, published Monday in the journal Nature.

MANILA: Golden Rice, announced two decades ago as the answer to Vitamin A deficiency, is nowhere near production.
In 2000, a Time magazine cover announced the sprouting of “Golden Rice”, promising to enhance nutrition for millions of poverty-stricken rice-eating Asians. The magazine showed the father of Golden Rice, Swiss plant researcher Ingo Potrykus, touting it as “rice that could save a million lives a year”. (1)
A diet of Golden Rice pale yellow because of genetically embedded beta carotene from which Vitamin A is made by the human body could bring rice-eating consumers the gift of life and sight.
