Less commonly, some children experienced a decrease in appetite. Later data on effectiveness (the vaccine's performance when used in the real world) for adults showed that the protection from the mRNA two-dose primary series wanes over time; but booster doses bring the immune system back to robust levels. Scientists engineer a harmless adenovirus (a common virus that, when not inactivated, can cause colds, bronchitis, and other illnesses) as a shell to carry genetic code on the spike proteins to the cells (similar to a Trojan Horse). The two doses are given 3 weeks apart. They can't cause COVID-19 because they only contain small purified pieces of proteins and not the virus itself.

The study found the bivalent vaccine to be 58.7% effective against hospitalization compared to 25% for the monovalent one that preceded it; its effectiveness against infection was 61.8% compared to 24.9% for the monovalent.
