The recent approval of a COVID vaccine for infants and preschoolers is a boost needed in Canada\u2019s ongoing battle with the pandemic, says Brock University immunologist Adam MacNeil.<\/p>\n

Health Canada announced Thursday that the Moderna vaccine has been approved for children between six months and five years old.<\/p>\n

\u201cThis is a monumental step toward maximizing the vaccine layer of protection across our communities as we continue to wrestle with the evolution of one of the most transmissible pathogens in human history and learn more about its long-term impacts on health outcomes,\u201d says MacNeil, Associate Professor of Immunology.<\/p>\n

The children\u2019s vaccine works in exactly the same way as the adult version, he says, with very mild \u2014 and no serious \u2014 side effects reported to date.<\/p>\n

\u201cAs a parent of an under-five-year-old myself, and someone who has dedicated significant time to studying immunity at its most fundamental level, I will absolutely be vaccinating my child,\u201d MacNeil says.<\/p>\n

At one-quarter the size of the standard adult dose, Moderna\u2019s latest vaccine takes children\u2019s smaller bodies into account, \u201cwith the lower dose being optimized to ensure a safe and effective immune response,\u201d he says.<\/p>\n

MacNeil explains that the children\u2019s dose contains 25 micrograms of messenger RNA (mRNA) as compared to the 100 micrograms found in the adult version. This will be translated into a protein and shown to the immune system to create a protective immune response in the form of antibodies and T cells, he says.<\/p>\n

\u201cThe bottom line is that independent scientific review of the evidence on vaccine efficacy has demonstrated that the benefits of receiving the vaccine outweigh the risks and that the immune response is similar to that seen in those 18 to 25 years old,\u201d he says.<\/p>\n

MacNeil notes that polio, diphtheria, pertussis, measles, smallpox and other pathogens have been completely or nearly wiped out thanks to routine childhood vaccination schedules.<\/p>\n

Meanwhile, COVID-19 continues to pose a threat to children. MacNeil says that in Ontario, 23 children from newborn to four years have recently been hospitalized for COVID, while a similar number is attributed to the entire five-to-39-year-old age range.<\/p>\n

Like many other viruses, COVID-19 infection may also have long-term effects that aren\u2019t fully understood yet, he says.<\/p>\n

He encourages parents who have concerns or questions about their children\u2019s unique situations to talk to their child\u2019s health-care provider.<\/p>\n

MacNeil says that while most or all people will likely be exposed to the COVID-19 virus at some point, research has shown multiple infections lead to increasingly negative health outcomes on the body\u2019s tissues and organs.<\/p>\n

\u201cThese aren\u2019t dice you want to roll,\u201d he says. \u201cYou want to catch this as few times as you can. Vaccines will help with that and protecting our youngest and most vulnerable is a big step toward minimizing the transmission chain with the tools we have available to us.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
