• Study Finds Increasing Time Between COVID Vaccine Doses Reduces Risk of Myocarditis, Yet Cardiologists Raise Concerns

  Expert says adolescents do not have trouble with COVID-19 and are being subjected to higher risk than benefit by being vaccinated.

  New research suggests increasing the interval between vaccine doses or using a single dose may significantly lower the risk of heart inflammation caused by mRNA COVID-19 vaccines. Yet some cardiologists are concerned about asymptotic myocarditis and say any risk of heart inflammation in a population group that’s not at risk of experiencing severe COVID-19 is too much.
  In a February peer-reviewed paper published in NPJ Vaccines, researchers in Hong Kong observed a significantly lower cumulative incidence of carditis, or heart inflammation, among adolescents who received their second vaccine dose more than 56 days after their first dose compared with those who received their second dose within 21 to 27 days. A second analysis showed that increasing the time between the first and second vaccine doses decreased the risk of heart inflammation by 66 percent. Researchers compared the risk of carditis between standard and extended interdose intervals in 12- to 17-year-olds who received two doses of Pfizer’s COVID-19 vaccine.

  Among 143,636 adolescents who received at least one dose of Pfizer’s COVID-19 vaccine, 130,970 (91 percent) received a second dose. Approximately 43 percent of these adolescents received their second dose at an extended interval. During the study period, a total of 84 adolescents were hospitalized for conditions related to heart inflammation within 28 days of the second vaccine dose. After implementing exclusion criteria, 49 cases remained and were attributed to COVID-19 vaccination.
