On The Road To Eliminate Rabies, Gavi Announces Plan To Improve Human Vaccination

Rabies has been in global health's crosshairs for years. Around the world, the viral infection kills about 70,000 people a year — and since as early as 2015, groups including Gavi, the Vaccine Alliance, have had plans to shore up vaccine efforts to reduce the number. At one point, Gavi planned to include human rabies vaccines in its 2021 investment strategy — but then the Covid-19 pandemic got in the way.

Now, it's finally taking action. On Thursday, Gavi announced a plan to expand global access to human rabies vaccines, reaching over 50 countries. Most of Gavi's efforts focus on vaccinating as many people as possible against common viral threats. But for rabies, it's confronting a different kind of challenge: providing vaccines for post-exposure prophylaxis to the right people, at the right time.

Rabies is one of few diseases that can be effectively treated by vaccines after exposure. Most often transmitted by a rabid dog bite, the virus enters through the bite and travels through peripheral nerves, then up the spinal cord and to the brain. Once it reaches the brain, the resulting inflammation is almost always fatal. Post-exposure prophylaxis, delivered soon enough after a bite, can slow and stop the virus's approach to the brain with a combination of wound washing, the rabies vaccine itself, and immunoglobulins.

According to the World Health Organization, 95% of rabies deaths occur in Africa and Asia — in large part due to the limited availability of rabies vaccines. In the United States, around 60,000 people annually receive post-exposure prophylaxis following potential rabies exposure, and just 1 to 3 rabies cases occur each year, the vast majority of which are fatal.

Ryan Wallace, deputy branch chief for the poxvirus and rabies branch of the Centers for Disease Control and Prevention, said that since the rabies vaccine is "responsive" and not "routine" like other vaccines with scheduled administration, challenges with procurement and distribution are inevitable.

"It's very difficult for a non-routine vaccine to be available in all places at all times," Wallace said. "A lot of those 70,000 people that die every year, they didn't even ask for a vaccine, they weren't aware, the health services weren't there, the veterinary services weren't there, and they didn't seek it."

The new program is aligned with the Zero by 30 campaign, a plan outlined by the WHO and others in 2018 to end human deaths from rabies transmitted by dogs by 2030. Gavi plans to prioritize reaching under-immunized children and disadvantaged communities. Low-income countries can apply for support for the rabies post-exposure prophylaxis vaccine starting in July of this year, with support based on the budgeting plan submitted by the country requesting aid. Gavi will not be providing support for immunoglobulins.

Charles Rupprecht, a WHO expert technical advisor on rabies and former chief of the rabies program at the CDC, said there's a misconception on what limits access to human rabies vaccines: It's not about manufacturing enough of the vaccines, but rather providing a way for countries to pay for them.

"There's no real shortage in biologics that producers can produce — either Big Pharma or smaller ones in some of the most effective markets," Rupprecht said. "The difficulty has been in trying to define what those markets are, and to try to define need and to prioritize rabies prophylaxis."

Vaccine banks "can bring lower prices and more stability to vaccine markets," Wallace said, by purchasing high-quality vaccines in bulk. "Resolving vaccine-access issues will take time, but initiatives like Gavi's human rabies vaccine program improve access to low-cost, high-quality human rabies vaccines."

There are challenges beyond acquisition. Terence Scott, director of programs at the Global Alliance for Rabies Control, said the biggest obstacle for governments is distributing vaccines from the national level to the people that need it most.

"We see that in many countries, the major district hospital will have supply of vaccine and post-exposure prophylaxis," said Scott. "But then in the more rural clinics, they won't have access to that."

Beyond mitigating issues with logistics of distribution and supply chain, Scott highlighted training of medical professionals and education of at-risk populations as additional prerequisites to ensuring Gavi's proposal is used effectively.

"It needs to be a multifaceted approach that encompasses things like education — educating people that when they are exposed, they need to go to the clinic and seek medical advice," Scott said.

In spite of potential challenges Gavi faces in implementing the program, Wallace expressed optimism on the eventual outcome.

"There's hundreds of thousands of lives that are going to be saved over the next decade through this program," Wallace said.

Dog And Cat Owners, Urged To Avail Of Free Anti-rabies Vaccination For Pets In Manila

Mayor Honey Lacuna is inviting Manila residents who have 'fur babies' to avail of the free anti-rabies vaccination that would be given on June 22 (Saturday).

Lacuna said the vaccination program, which is a joint effort of the Manila city government, the JCI Manila and the Veterinary Inspection Board of Manila, would cover pet dogs and cats.

According to the mayor, the purpose of the program is to help provide safety not only for the pets concerned but more so, for the members of the community.

It was learned that the program will be held from 8 a.M. To 11 a.M. At the Canonigo Basketball Court located on Pres. Quirino Extension, Brgy. 678 Zone 74 in Paco, Manila.

Lacuna, who is also a doctor, stressed the importance of availing of free anti-rabies vaccination if one has pets, noting that rabies may cause death and can be transmitted from animals to humans.

Pets that have been vaccinated enjoy better protection and become healthier and more active, she said.

She urged the residents of Manila to join hands in the effort to have all pets in the city vaccinated and do their share in ensuring that all communities within the city will be safe and healthy at all times.

On the said date, Lacuna said that in addition to giveaways, free flyers will also be distributed. These flyers contain information about the correct way of taking care of a cat or dog, how to keep them healthy and what should be done in case one gets bitten or scratched by said animals.

Meantime, those who are not able to avail may go to the city's health centers under Manila Health Department chief Dr. Arnold 'Poks' Pangan where free anti-rabies vaccination services are also being offered.
