COVID vaccine: Is the time of day you get the shot important?

Can the time of day a person gets the coronavirus vaccine play a role in how many antibodies will be made in their body? It is possible, according to a new American-British scientific study. In particular, the study found that people who are vaccinated in the afternoon usually appear to have a better immune response than those who are vaccinated in the morning. However, it is worth mentioning that this finding should be confirmed by other research. Researchers at Harvard and Oxford University, led by Dr. Elizabeth Clerman of the Harvard Medical School and the Department of Neurophysiology at Massachusetts General Hospital analyzed the finding of nearly 2,800 healthcare professionals in the UK who had been vaccinated with Pfizer / BioNTech or AstraZeneca vaccines. The antibody response after vaccination was found to be generally higher in all those vaccinated after noon. Those with the Pfizer vaccine, women and younger adults also had a stronger immune response. “Our observational study provides solid evidence that daylight hours affect the immune response of the vaccination, and these findings may be taken into account to improve vaccine efficacy,” said Clermann. Previous studies have found that in the case of the flu vaccine in the elderly, antibody levels were higher in those who had been vaccinated in the morning. “The Covid-19 vaccine and the flu vaccine have different mechanisms of action, and the immune response can vary considerably depending on whether the immune system recognizes the pathogen from previous infections, such as the flu, or whether it is a new virus like the coronavirus “. As she added: “We need to repeat our findings and develop a better understanding of the underlying physiology of Covid-19 and the body’s response to vaccination before recommending it to people who want to take an extra dose, such as the elderly”.
