MORE OPTIONS ENTERING THE VACCINE GAME, BUT VARIANTS LOOM LARGE — Maryland biotech Novavax released welcome news Thursday that its Covid-19 vaccine is 89 percent effective in a late-stage trial. The catch: The shot is significantly less effective against the strain first found in South Africa. South Carolina on Thursday reported the first known cases of that strain in the U.S. It’s a notable gap. Moderna said earlier this week that its own vaccine, using messenger RNA technology, is slightly weaker against that variant but still protective. But Novavax reports that its shot is just 49.4 percent effective after a phase IIb study in South Africa. Company executives told investors they are in conversations with FDA about whether the data from the U.K. and South African trials will enable Novavax to apply for emergency use authorization. Officials have been worried about this. Top infectious disease expert Anthony Fauci told POLITICO this week that the South African variant is “problematic” and it is “prudent” for companies like Moderna to get to work on a booster shot. Pfizer, maker of the other authorized Covid-19 vaccine along with BioNTech, also says it is exploring the data to understand its shot’s efficacy against the emerging variant. In the meantime, the Centers for Disease Control and Prevention is recommending against travel right now, while the White House is banning visits from South Africa and much of Europe and requiring negative tests from Americans returning from those countries. Don’t forget: Johnson & Johnson, maker of the single-dose candidate, should release data for its single-dose shot today. WHAT IS GOING ON WITH THE ASTRAZENECA VACCINE? European leaders are increasingly frustrated with the British drugmaker after a shortfall in vaccine doses. Some regional officials are calling on AstraZeneca to publish its production contracts while others say it could be time to invoke emergency provisions that steamroll patents. The anger comes after a production lag and comments by AstraZeneca CEO Pascal Soriot in the Italian newspaper La Repubblica — noting caveats to the agreement and saying the company is making its “best efforts” to supply 100 million vaccines. Remember: The United Kingdom and a handful of other countries have authorized the AstraZeneca and Oxford shot; the European Union is expected to approve its use today. While U.S. regulators have not weighed in on the vaccine yet, the government did order 300 million shots from the manufacturer. European Union officials are struggling to close up the gap on vaccine supplies, our POLITICO Europe colleagues report. Authorities have threatened to get their money back — a €336 million down payment — if AstraZeneca doesn’t deliver all its promised doses for the first quarter, writes Jillian Deustch. And European Council President Charles Michel on Thursday also said the EU could invoke emergency provisions in the region’s treaties to meet the shortfall. Those could include forcing vaccine makers to share their patents and other licenses to ramp up production, David Herszenhorn writes. MEANWHILE: ANOTHER MANUFACTURER LENDS A HAND — French drugmaker Sanofi announced this week that it will help Pfizer and its German partner BioNTech with bottling Covid-19 vaccines destined for Europe. Production won’t start until July, but Sanofi CEO Paul Hudson told Le Figaro that the company should be able to chip in 100 million doses by the end of the year. They will churn out of Sanofi’s Frankfurt facility, which isn’t far from BioNTech’s headquarters. The news comes after Sanofi’s own Covid-19 vaccine attempt, developed with GSK, failed to show sufficient immune response in older adults in early trials, delaying its production until late 2021. |
