What Happened When Sweden Stop Using the DPT Vaccine?

Do you ever wonder what would happen if we stopped vaccinating our kids?

You don’t have to wonder.

What Happened When Sweden Stop Using the DPT Vaccine?

It’s been done…

Remember when Sweden stopped using the DPT vaccine?

Endemic pertussis returned when they stopped using the DPT vaccine in Sweden.

Between 1979 and 1996, Sweden suspended vaccination against pertussis because of concerns about the DPT vaccine.

And what happened?

“In 1979, the Swedish medical society abandoned whole-cell pertussis vaccine and decided to wait for a new, safer, more effective vaccine – a strategy that was soon adopted as national policy. During 1980-83, annual incidence for children aged 0–4 years increased to 3370 per 100000, with rates of serious complications approaching global rates. In subsequent years, Sweden reported more than 10000 cases annually with an incidence exceeding 100 per 100000, comparable to rates reported in some developing countries.”

Pertussis came back.

In fact, endemic pertussis came back.

“Our evaluation of pertussis in the unimmunized child population gave an answer to the question of whether pertussis nowadays is a harmless disease which does not demand general vaccination. The present situation regarding pertussis in Sweden and the low efficacy of the antimicrobial treatment indicate an urgent need to prevent the disease by general vaccination as soon as a safe and effective vaccine is available.”

Of course, they already had a safe and effective vaccine at the time.

All of the claims against the whole cell pertussis vaccine ended up being untrue.

The incidence of SIDS didn't drop when they stopped using the DPT vaccine in Sweden.

Not surprisingly, even though they weren’t using the DPT vaccine, rates of SIDS didn’t drop until they implemented the back to sleep recommendations.

If vaccines are associated with SIDS, shouldn’t the incidence of SIDS have decreased when they stopped giving infants the DPT vaccine?
