NOTICE PAPER NO. 1769 
NOTICE OF QUESTION FOR ORAL ANSWER
FOR THE SITTING OF PARLIAMENT ON 3 MARCH 2023

Name and Constituency of Member of Parliament
Mr Yip Hon Weng
MP for Yio Chu Kang

Question No. 4297

To ask the Minister for Health (a) what are the latest statistics on incidence of myocarditis post-mRNA vaccination; (b) whether there has there been a change in the incidence with the bivalent vaccines; and (c) whether the Government will make it mandatory for those involved in strenuous labour in the workforce to be given two weeks of light duty after their mRNA vaccination. 

Answer

For the period up to 31 December 2022, the reported rate for myocarditis is 1 per 1,000,000 doses for the bivalent mRNA vaccines, compared to 11 per 1,000,000 doses for the monovalent mRNA vaccines.

Since September 21, MOH have advised individuals to avoid strenuous exercise or physical activity for two weeks following any dose of the mRNA vaccine as a precaution. The World Health Organisation and many international jurisdictions, including the USA and UK, do not recommend this unless there are symptoms post vaccination.

Many work activities such as walking, and working while standing, are not strenuous and workers can continue with them as long as they are well. However, the level of physical exertion differs between jobs, settings and individuals. Employees and employers should discuss work arrangements so that employees can work safely after vaccination.
