MVEC has recently updated its RSV reference page with a new FAQ addressing whether there is an increased risk of preterm birth associated with RSV vaccines in pregnancy.
Current data has not demonstrated a statistically significant risk of preterm birth associated with Abrysvo. A trial of a different RSV vaccine was halted due to a difference in the number of preterm births in the vaccine group compared with the placebo group.
Find MVEC’s detailed answer in the ‘Commonly asked questions’ section of the MVEC：呼吸道合胞病毒（RSV） reference page, under the question ‘Is there an increased risk of preterm birth associated with RSV vaccine in pregnancy’.
