Their analysis of medical data suggests that boys aged 12 to 15, with no underlying medical conditions, are four to six times more likely to be diagnosed with vaccine-related myocarditis than ending up in hospital with Covid over a four-month period. Most children who experienced the rare side-effect had symptoms within days of the second shot of Pfizer/BioNTech vaccine, though a similar side-effect is seen with the Moderna jab. About 86% of the boys affected required some hospital care, the authors said. Saul Faust, professor of paediatric immunology and infectious diseases at the University of Southampton, who was not involved in the work, said the findings appeared to justify the cautious approach taken on teenage vaccines by the UK’s Joint Committee on Vaccines and Immunisation. The JCVI did not recommend vaccinating healthy 12 to 15-year-olds, but referred the matter to the UK’s chief medical officers who are expected to make a final decision next week. Children aged 12 to 15 who are particularly vulnerable to Covid, or who live with an at-risk person, are eligible for the shots. In the latest study, which has yet to be peer reviewed, Dr Tracy Høeg at the University of California and colleagues analysed adverse reactions to Covid vaccines in US children aged 12 to 17 during the first six months of 2021. They estimate the rate of myocarditis after two shots of Pfizer/BioNTech vaccine to be 162.2 cases per million for healthy boys aged 12 to 15 and 94 cases per million for healthy boys aged 16 to 17. The equivalent rates for girls were 13.4 and 13 cases per million, respectively. At current US infection rates, the risk of a healthy adolescent being taken to hospital with Covid in the next 120 days is about 44 per million, they said. How reliable the data is and whether similar numbers could be seen in the UK if healthy 12 to 15-year-olds are vaccinated are unclear: vaccine reactions are recorded differently in the US and shots are given at longer time intervals in the UK. According to the UK medicines regulator, the rate of myocarditis after Covid vaccination is only six per million shots of Pfizer/BioNTech. So far, UK children have not been admitted to hospital for Covid in large numbers and may not be at great risk of long Covid. While the recent Clock study found that up to 14% of children who caught Covid may still have symptoms 15 weeks later, levels of fatigue appear similar to those in children who have not caught the virus. This suggests that children may be spared some of the most debilitating problems seen in adult long Covid.
这两个数字不能直接比较啊 They estimate the rate of myocarditis after two shots of Pfizer/BioNTech vaccine to be 162.2 cases per million for healthy boys aged 12 to 15 and 94 cases per million for healthy boys aged 16 to 17... At current US infection rates, the risk of a healthy adolescent being taken to hospital with Covid in the next 120 days is about 44 per million, they said. 打疫苗的94/Mil是打了一百万疫苗，有94个住院 后面的44/Mil是所有该年龄段的青少年（把没得covid的也考虑进去了）
Boys more at risk from Pfizer jab side-effect than Covid, suggests study
