No, from a "herd immunity" perspective just vaccinating the girls should be pretty effective. Assuming girls only transmit the virus to boys and boys only transmit it to girls (I know, not PC, but a good first approximation), then if you only have resources to vaccinate half the population, it's much better to vaccinate all the girls than a random sample of the population. The article is specifically arguing that boys should get vaccinated for their own benefit - not a herd immunity argument.
