Before the discovery of antibiotics, tuberculosis was the second most common cause of death in the US. Today, thanks to antibiotics, the few who contract the disease rarely die.

But as TB and other once-easily cured diseases grow increasingly antibiotic resistant, the very real fear is that medicine may run out of treatment options, leading to epidemics dwarfing COVID-19.

To head-off that kind of future, two dozen pharmaceutical firms have invested nearly $1 billion creating the AMR Action Fund with the goal of developing 2-4 new antibiotics by 2030.

AMR – antimicrobial resistance – arises when infectious disease pathogens become resistant to existing medicines. Tuberculosis is one of them, as are several others including the much publicized MRSA.

“AMR has the potential to render diseases that are relatively easy to treat today virtually incurable,” said Dr. Paul Stoffels, vice chairman of the executive committee and chief scientific officer, Johnson & Johnson.

“Left unchecked, AMR could significantly eclipse the global health challenge that the world is facing currently with COVID-19,” he said in a statement announcing the launch of the AMR Action Fund.

The initial funding pledges from the bioscience and drug firms – including $100 million pledged each by Johnson & Johnson and Pfizer – will be supplemented by non-industry partners, the Fund says on its website.

Explaining that “drug resistant bacteria are developing faster than new antibiotics can reach the market,” the Fund says there are few antibiotics in clinical development to meet current and anticipated needs. The reason is that the market for antibiotics “doesn’t support the level of investment needed to maintain a robust antibiotic pipeline.”

The website goes on to explain that smaller biotech firms have trouble financing trials of the antibiotics they do develop. Some that have developed new antibiotics “have declared bankruptcy or exited this space,” cautions the Fund, “Due to the lack of commercial sustainability, resulting in the loss of valuable expertise and resources.”

To achieve its goal of bringing to market the new antibiotics in a decade, the Fund said it “will invest in smaller biotech companies focused on developing new antibiotics that address the highest priority public health needs.”

Specifically, the AMR Action Fund will:

  1. “Invest based on the WHO/CDC priority lists of pathogens, with the goal to address major unmet needs and maximize public health impact.
  2. “Prioritize novel antibacterial treatments, as recognized by leading public health agencies, with significant and differentiated clinical utility and that reduces patient mortality.
  3. “Invest across all stages of clinical development.”

What’s the Difference Between the COVID Vaccines?

With the approval last month of the Moderna vaccine by the Food and Drug Administration, we now have two COVID-19 vaccines available. Two more – one from Johnson & Johnson the other from AstraZeneca – are on the way and could be approved as soon as February.

Healthcare workers, residents of nursing facilities and some first responders have already received the Pfizer vaccine, the first one approved by the FDA. Moderna has begun shipping its vaccine with the first of the 25 million initial doses administered last month.

People eager to be immunized have inundated doctors’ offices and clinics asking when the vaccine will be available. The best answer is soon.

Which one, though, will you receive? And does it make any difference?

The answer to the first question is whichever vaccine can be obtained the quickest or, in some cases, whichever your health plan recommends. It really doesn’t make any difference to you.

Both vaccines require two separate doses to reach maximum effectiveness 21 days apart for Pfizer and 28 days for the Moderna version. Both protect about equally well. The FDA data shows Pfizer is 95% effective after both doses. Moderna is 94.1%.

Unlike most other vaccines, these two vaccines use pieces of protein from the SARS-CoV-2 virus to prompt the body to create antibodies. Conventional vaccines, like the annual flu shot, are manufactured from viruses typically grown in chicken eggs. These chicken grown viruses are then killed or weakened to become vaccines.

The COVID vaccines employ messenger RNA (mRNA), a newer technology. These vaccines “teach” the body to replicate the little bit of the CoV-2 protein, which, in turn, creates an immune response causing the body to make the antibodies that provide the protection against the virus.

The most significant difference between the Moderna and the Pfizer vaccines is how they must be stored. Both can survive for a few days in standard refrigeration. For longer periods, the less stable Pfizer vaccine must be kept in ultra-low temperatures below -94 F. That makes shipping and storing Pfizer’s vaccine somewhat more complicated, especially outside urban areas where the low temperature refrigeration is not easily available.

“At the end of the day, these two vaccines are pretty similar,” Dr. Thomas Russo, professor and chief of infectious disease at the State University of New York, tells Health. “Grab it while you can.”
