even though today there is vastly improved technology, medical knowledge and communications, there are still challenges in overcoming vaccine resistance and hesitancy, observed hammond.
those include, for some people, a deep distrust of various kinds of authorities that interlock with other attitudes and assumptions including political, which are also fanned by access to information sources that are not scientifically valid, noted hammond.
“it makes it almost harder for the more advanced countries in some ways, paradoxically. we have a more fragmented media environment and more avenues for people to stand up and say, ‘no, this is bad for me, and i don’t want to do this’,” said hammond.
it may, as in the past, simply take time to overcome vaccine resistance and change attitudes, he said.
smallpox vaccines were first developed in the 1790s and were widely available by the 1810s.
yet, it still took another 170 years for smallpox to be declared eradicated, said hammond.
the delta variant, a virus mutation of the coronavirus that caused covid-19, first identified in india, now accounts for more than 90 per cent of cases in b.c.
research, including that compiled by the u.s. centre for disease control, indicates the delta variant may be twice as contagious as previous variants and may cause more serious illness than previous strains in unvaccinated people.
