Vaccines: world needs new approach, more transparency, say researchers

鈥淲e can鈥檛 just have a group of clever people go off into a room and make a decision," says Natasha Crowcroft

A group of 重口味SM researchers is urging the world鈥檚 health authorities to overhaul the way vaccine decisions are made and communicated, saying such decisions should no longer be made behind closed doors. 

The decision by government authorities to include new vaccines on their countries鈥 schedules should be open to public consultation and input, and the process should allow greater prominence to ethical considerations, they argue.
 
Babies today receive far more protection from disease through vaccination than children in previous generations, and the diseases that are targeted by newer vaccines are now relatively rare, said Natasha Crowcroft, associate professor in U of T's department of laboratory medicine and pathobiology. As a result, decisions about whether to schedule additional vaccines are more difficult and require more than just scientific input  鈥 and the traditional, closed-door method of deciding whether a new vaccine should be used is outmoded. 
 
鈥淎nything that undermines confidence in immunization is a bad idea,鈥 said Crowcroft, who is also chief of infectious diseases at . 鈥淲e can鈥檛 just have a group of clever people go off into a room and make a decision. That process doesn鈥檛 work anymore.鈥
 
In a paper published Jan. 30 in the , Crowcroft, along with Professors Ross Upshur and Shelley Deeks of U of T's , calls for an internationally agreed-upon framework to provide clarity about the pros and cons of adding new vaccines to the schedule. 
 
鈥淓very country is facing the same decision,鈥 Crowcroft said. 鈥淚t has to be international because we鈥檙e all in this together. Disease can鈥檛 be turned back at the border. And every country is struggling with the same issue 鈥 there鈥檚 a crucial chunk missing from the decision-making process which undermines public confidence.鈥
 
The way in which British health authorities handled the decision against introducing a new vaccine in 2013 underscores the need for change, according to the authors. Authorities announced they were declining the vaccine for meningitis B, a rare but harsh disease affecting babies, because it was not cost effective 鈥 triggering a public outcry.
 
While it may have seemed easiest to put it in strictly economic terms, in reality the initial decision to turn down the vaccine was far more complex, involving safety and effectiveness considerations, said Crowcroft. But the public never understood the nuances because such decisions are made behind closed doors. In the British case, this lack of transparency led to conspiracy theories, including the idea that industry had unduly influenced the proceedings.
 
The authors also believe that bio-ethicists should be involved in the decision-making process early on, when the risks and benefits of a new vaccine are being weighed. Ethical considerations, such as the opportunity cost of spending health care dollars on vaccinations, should be integral to the assessment of the medical evidence and economic benefit of an immunization, they argue.
