Vaccinations save lives. Measles outbreaks tells us that some people aren’t getting the message – Toronto Star

Vaccines don't save lives. Vaccinations save lives.

A vaccine in an arm, on the other hand, can save the world. Childhood vaccination prevents about 4 million deaths each year, and the World Health Organization estimates that the measles vaccination saved 56 million lives between 2000 and 2021.

Yet far too many measles vaccines still remain in their vials, with global immunization coverage at only 74 per cent in 2021, far from the 95 per cent required to prevent outbreaks.

As a result, measles cases worldwide increased by 79 per cent in 2023, with the WHO European Region of particular concern: Last year, 41 of its 53 member states tallied 58,000 cases, a dramatic rise from just 941 cases in 2022.

Canada has so far been spared that catastrophic increase, but were seeing worrying signs this year. Seventeen cases were confirmed as of Monday, with infections in British Columbia, Saskatchewan, Ontario and Quebec.

Quebec public health director Luc Boileau reported 10 cases in that province alone, including seven in Montreal. And while some infections were likely acquired through international travel, community spread now seems evident.

That spread could continue since only 78.5 per cent of Montreal elementary school children are vaccinated. And according to Mylene Drouin, the citys public health director, vaccination rates have fallen below 50 per cent in some areas.

Montreal is therefore at significant risk of a major outbreak, but its not alone. According to the 2021 National Immunization Coverage Survey, just 79.2 per cent of seven-year-old children across the country are fully vaccinated, meaning theyve received two doses of the vaccine.

Even worse, the percentage of fully vaccinated seven-year-olds has been dropping steadily, from 87 per cent in 2017, and 83.3 per cent in 2019. Vaccination rates among two-year-olds -- who receive only one dose -- are substantially higher, but the decline in the percentage of fully immunized elementary school age children remains troubling.

The rise of anti-vaccination sentiments during the COVID-19 pandemic might be playing a role in this decline, though according to the immunization survey, only 2.5 per cent of parents said the pandemic made them less inclined to vaccinate their kids.

That said, the survey did find that nearly half of parents fear vaccine side effects, and an increasing percentage believe that alternative medicine and healthy lifestyles can replace the need for vaccination.

A February Angus Reid poll echoed those findings, with one in three respondents saying theres a real risk of serious side effects from vaccines, and 22 per cent insisting that the human body doesnt need vaccines to build immunity.

These beliefs, along with related ones such as a general lack of trust in vaccines, led one in six Angus Reid respondents to say that they were really against vaccinating their kids -- a fourfold increase since 2019.

Reversing this trend is imperative if were to avoid major outbreaks in the future, and fortunately, most Canadians are open to receiving new information and changing their minds.

In fact, a by the Canadian Vaccination Evidence Resource and Exchange Centre (CANVax) found that parents wanted more information than they were getting (mainly balanced information about benefits and harms), presented clearly and simply, and provided in good time.

Health care providers are, of course, key to disseminating such info. But beyond that, the CANVax and other reviews found positive effects from both mass vaccination campaigns and smaller efforts aimed at addressing the concerns -- such as side effects -- of specific communities and individuals.

Local campaigns can also benefit from the support of community, faith and industry leaders, who often enjoy significant trust in their communities. And novel approaches to conveying information, including the use of narratives instead of merely presenting statistics, can bolster efforts to overcome vaccine hesitancy.

To reverse declining vaccination rates, then, we need to engage in a thorough, multi-faceted effort, and to act like vaccinations can save our lives. Because they can.
