A world-first study has found that children undergoing cancer treatment responded well to COVID-19 mRNA vaccinations.
Associate investigator and medical oncologist at Monash Health, Dr Amy Body, said the objective of the trial was to understand how well the COVID-19 vaccine works in children with cancer, who are often undergoing treatments that reduce their immune responses.
‘Due to their treatment, these children are at increased risk of becoming severely unwell with COVID-19. But the information regarding the effectiveness of vaccination for these children was limited,’ she said.
The paper published in The American Academy of Paediatrics concluded that its data suggest vaccination during treatment may be more effective than previously thought, supporting the administration of primary vaccinations during treatment and booster doses at completion, rather than deferring vaccination altogether.
But it added one caveat to vaccinating patients undergoing treatment: to avoid live vaccines such as measles, mumps, rubella, and varicella due to safety concerns.
The study also noted that mRNA vaccines used in this study differ from current childhood vaccinations and may have a greater ability to stimulate the immune system compared to traditional vaccinations.
