For the most part, the experts were severe even adhere to theRecommended intervals Between your Covid vaccine shots if you make a two-dose diet. For Pfizer, you are supposed to wait three weeks between injections, while Moderna requires four weeks. Centers for Disease Control and Prevention (CDC) reported that you should notexceed these intervals If "delay is inevitable", and even then, it should not go past 42 days. However, a recent study revealed that when people 80 and over their delay second pfizer shot, they have more antibodies.

The study was conducted by the University of Birmingham with public health in England. Research published on May 14, found thatAntibody response With 80 years and over was three and a half times higher when they delayed the second dose of the Pfizer vaccine for 12 weeks, compared to those who received it with the recommended three-week interval. In addition, the researchers concluded that the administration of the second dose after 12 weeks can potentially improve and expand antibody immunity, which plays a vital role in the neutralization of the virus and the prevention of infection.

While the United States continues to join the three-week interval and suggests that pushing the second dose to 42 days, other countries still extended the second injection. On December 30, R.U. Chief Medical Officers released a statement that the first and second doses of Pfizer and AstraZeneca vaccines can be takenUp to 12 weeks apart.

Although Covid vaccination is in progress, experts still have a lot to learn about the best way to vaccinate against this virus. "Many questions remain about optimal delivery vaccines for the provision of effective and sustainable immunity", author of the studyHelen Parry, PhD, said in the declaration. This study was the first to examine the antibody response to the vaccine when given after such a prolonged period of time. "This research is crucial, especially for the elderly, as immune responses to vaccination deteriorate over time," said Parry. "Understand how to optimize COVID-19 vaccination schedules and maximize immune responses within this age group is vitally important. »

The results of this study are not only beneficial for people aged 80 and over, but also help guide vaccination efforts in general. "Improved antibody responses observed after an extended interval can help maintain long-term Covid-19 immunity, and further improve the clinical effectiveness of this powerful vaccine platform," co-author "Moss paul, PhD, said in the declaration.
