FDA Opposes Dilution of COVID-19 Vaccine Doses: Here's Why

Following the approval of three coronavirus vaccines for emergency or conditional use in some countries last month, some experts are now advocating changes in approved dosing regimens. The vaccines include Pfizer and partner BioNTech’s BNT162b, Moderna’s mRNA-1273 and AstraZeneca’s AZD1222. The change in dosing will help to vaccinate a larger number of people amid rising cases of infections. On the other hand, the FDA has opposed any changes to dosing regimens as it may lead to unnecessary risks to public health.

Please note that while BNT162b is approved in more than 40 countries including the United States and Europe, mRNA-1273 is approved in the United States, Canada and Israel. AZD1222 is approved in the United Kingdom and India. These vaccines are under review in multiple other countries and approval in many of them are expected soon. The currently approved dosing regimen for these vaccines are two full doses separated by three or four weeks.

Rising Cases

In the United States, the coronavirus has infected a total of approximately 20.5 million people and claimed nearly 349,000 lives so far, per World Health Organization’s (WHO) website as of Jan 5. Moreover, daily new cases of infection are also surging, reaching almost 300,000 earlier this month in the country, per the same website.

A similar scenario is also being observed in the United Kingdom where, per WHO website, daily new cases has crossed the 58,000-mark, reflecting an almost similar daily new cases to population ratio in the United States. However, growth in daily cases seems to have slowed down in Europe but a sudden bout can change the scenario.

With spiraling COVID-19 infection cases, mainly in the western countries including the United States, there is a scramble for doses of these approved vaccines. Although there are supply agreements in place, the rising infection rates are increasing the burden on healthcare facilities. The available doses are not enough to inoculate everyone.

Governments are looking for ways to accelerate inoculation of citizens for containing the risk of spread of the virus as soon as possible. Meanwhile, a new strain of the coronavirus, reportedly found in the United Kingdom, is ringing alarm bells as it is potentially more contagious than the original strain found in 2019. Moreover, the companies with approved or under development vaccines are yet to test their candidates for immunity against the new strain.

Dosing Regimen Changes

The dosing regimen changes recommended by experts  include inoculation with only one dose, delaying the second dose, vaccinating with half of approved dose volume or vaccinating with two different vaccines. These changes should help increase the number of inoculations with available doses.

Reportedly, the World Health Organization and U.S. government’s Operating Warp Speed head, Moncef Slaoui, are open to changes in the dosing regimens of the approved vaccines.

FDA’s Refusal

The FDA stated in a press announcement that changing of dosing regimens are reasonable options for evaluation in clinical studies. The FDA authorized the coronavirus vaccines and their dosing regimens based on the totality of scientific evidence. The regulatory agency stressed that any changes to it must be backed by clinical study data. 

Changing the dosing regimen may change the nature of the depth and duration of protection, which is concerning. The agency has strongly recommended the use of approved dosing regimens without any change to avoid any health risk. Moreover, Slaoui stated that the FDA will have the last say on changes in the dosing regimens of the coronavirus vaccine in the United States.

Meanwhile, Moderna has raised its base production target for mRNA-1273 for 2021 by 100 million doses. Other companies need to follow suit for proper inoculation of the majority of population across the globe by the end of 2021.

While Moderna carries a Zacks Rank #2 (Buy), Pfizer, BioNTech and AstraZeneca carry a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
