The U.S. is the last major power to enter the race for global vaccine diplomacy, but still has the opportunity to win it.

Why it matters: China, Russia and other world powers began shipping vaccines all over the world months before the U.S. But they've all run into serious obstacles that leave the U.S. with an opening to become the biggest piece in the global vaccination puzzle.

The big picture: China has given or sold doses of its vaccine to around 90 countries, and 70 nations expect to receive Russia's Sputnik V vaccine, per the Economist Intelligence Unit. Those include nearly every country in Latin America.

  • The Biden administration has expressed concerns that Moscow and Beijing could use vaccines as leverage to expand their global influence.
  • Both governments stand to profit commercially from their state-funded vaccine, and diplomatically from the positive headlines the shipments produce.

Yes, but: Both have also struggled to deliver on their promises, as have the other major players: India and the EU.

That leaves the U.S., which is second only to China in terms of production but has barely exported any vaccine doses at all.

  • A major domino fell when President Biden agreed to export the U.S.' AstraZeneca stockpile.
  • Now, the White House has backed Pfizer's plan to begin to export doses made in the U.S., and announced that at least 10% of all doses purchased by the U.S. will be exported by July 4.
  • With its enormous production capacity and dwindling domestic demand, the U.S. could soon pivot to churning out highly effective vaccines — from Pfizer, Moderna, Johnson & Johnson and soon Novavax — for the rest of the world.

Where it stands: China has exported more doses than all the other major players combined — which it can afford to do because its domestic outbreak is largely under control — through a combination of commercial sales, loan deals and donations to friendly countries.

  • But China's homegrown vaccines are less effective than others on the market. Chile has found the Sinovac vaccine offers little protection against symptomatic infections after one dose, and 67% after two. A study in Brazil put the efficacy at just 50%.
  • In countries like Brazil and Hungary, the refusal rate for Chinese-made vaccines is much higher than for western alternatives.
  • The director of China’s CDC acknowledged last month that the efficacy rates for China’s vaccines were “not high.” Discussion of those remarks was quickly censored online in China, per the FT.

Between the lines: An exercise intended in part to show China’s scientific and manufacturing prowess has had mixed results, even as China leads the way on exports.

Russia’s vaccine appears to be far more effective, at least based on one peer-reviewed study published in February, but it has run into troubles of its own.

  • Brazilian regulators recently rejected the vaccine, citing quality-control issues and inadequate data.
  • Russia's limited manufacturing capacity has also left it lagging behind the other major players. It's now hoping that other countries will produce its Sputnik V vaccine for their own domestic use, similar to a deal struck last week with Mexico.
  • France and Germany are considering buying it, but the EU’s foreign policy arm recently accused Russia of using Sputnik V — and misinformation about other vaccines — to "undermine public trust" in the bloc's approach to vaccination.
  • And Slovakia’s prime minister resigned last month over his controversial decision to buy Sputnik V doses, which the country’s drug agency refused to approve.

The EU, meanwhile, has struggled to live up its own rhetoric around “equitable access” to vaccines.

  • While drugmakers have been consistently exporting doses from the EU, the bloc's slow rollout forced Brussels to modify its export policy and pause plans to donate doses to developing countries.
  • The latest: France recently became the first rich country to donate doses to the global COVAX initiative, but the scale (100,000 doses) is a drop in the bucket compared to the gap left by India, which was until recently powering COVAX almost single-handedly.

India has exported doses to over 90 countries, including donations to neighbors, allies and several Caribbean islands.

  • But New Delhi froze most exports in March in order to prioritize the crisis at home.
  • The African CDC is warning that a prolonged pause would be catastrophic for lower-income countries that are counting on COVAX.

What to watch: Biden has said he wants the U.S. to play a central role in supplying vaccines to the world, but he hasn't yet said when or how.

U.S. approves third vaccine dose for certain immunocompromised people

The Food and Drug Administration and the Centers for Disease Control and Prevention have both recommended that certain immunocompromised people receive a third dose of the Pfizer-BioNTech or Moderna vaccine.

Why it matters: Data suggest that people with weakened immune systems don't generate strong enough levels of protection against the virus with just two doses, but a third dose could significantly help.

CDC head warns unauthorized boosters undermine safety monitoring

Rochelle Walensky, director of the Centers for Disease Control and Prevention, warned Thursday that Americans getting unauthorized booster shots of the COVID-19 vaccine undermine the CDC's safety monitoring of recipients.

Why it matters: With booster shots a near inevitability, many Americans are eager to know when they will be able to get one. Some are now circumventing official CDC guidelines and getting a third shot.

Health care's burnout crisis

Health care workers on the front lines in the fight against COVID are suffering from unprecedented levels of burnout amid the latest surge.

Why it matters: America’s health care workers are already burnt out from previous waves of the pandemic. But as hospitals in hotspots are filling up, and sick COVID patients are once again requiring life-saving care, the stress is being compounded by the battle over public health measures.
