Avoiding strenuous activity after vaccination

On 21 June 2021, I filed a Parliamentary Question for the Minister for Education, to ask whether schools will grant students at least one week of excuse from strenuous physical activity in school after each dose of a Covid-19 vaccine. I also asked whether schools will carry out active monitoring of students’ condition post-vaccination to detect symptoms of myocarditis or pericarditis, which are inflammations of the heart muscles.

In his answer on 6 July, the Minister said schools will excuse students from physical activity for one week after receiving their Covid-19 vaccination, whether it is for the first or second dose, and that PE and CCA teachers will check in with students before the start of physical activities.

I note that the Expert Committee on Covid-19 Vaccinations also updated its advice on 5 July that people should avoid exercise or strenuous physical activity for a week after any dose of the jab. They had previously advised this only after the second dose. This comes after the news of a 16-year old boy in Singapore who suffered a heart attack six days after receiving his first dose of the vaccination, which is still under investigation to understand the underlying cause.

Here is the full Parliamentary question and the Minister’s answer on 6 July 2021:


SCHOOLS TO GRANT STUDENTS EXCUSE FROM STRENUOUS PHYSICAL  ACTIVITY AFTER EACH DOSE OF COVID-19 VACCINE AND CARRY OUT  ACTIVE MONITORING OF STUDENTS’ CONDITION POST-VACCINATION 

Mr Gerald Giam Yean Song asked the Minister for Education (a) whether  schools will grant students at least one week of excuse from strenuous physical activity in  school after each dose of a COVID-19 vaccine; and (b) whether active monitoring of  students’ condition post-vaccination will be carried out to detect symptoms of  myocarditis or pericarditis. 

Mr Chan Chun Sing: Schools and Institutes of Higher Learning (IHLs) will excuse  students from physical activity for one week after receiving their COVID-19 vaccination,  whether it is for the first or second dose. All PE and CCA teachers will check in with  students before the start of these activities. We have also advised all parents and students  to be mindful of any potential side effects from the vaccination. In particular, if they were  to develop chest pain, shortness of breath or abnormal heartbeats, students should seek  medical attention promptly. 

MOH and the Health Sciences Authority (HSA) have also been closely monitoring  recipients of the mRNA COVID-19 vaccines. On 12 June 2021, MOH issued a circular to  all registered medical practitioners to ask them to be vigilant in detecting inflammatory  conditions affecting the heart muscles and outer lining of the heart respectively, when  assessing patients who have been recently vaccinated with the mRNA COVID-19  vaccines. 

Medical practitioners are also urged to report all serious adverse reactions, including  myocarditis and pericarditis, to HSA as soon as possible, so that swift regulatory actions  can be taken where necessary. 

MOE will continue to work with MOH and HSA to closely monitor students who  have experienced adverse reactions after the vaccination to ensure that suitable and appropriate care is given to these students. We will review and update our guidelines if  needed, to ensure the safety and well-being of students.
