The vaccine antigen technology, developed by the University of Cambridge and spin-out DIOSynVax in early 2020, provided protection against all known variants of SARS-CoV-2 – the virus that causes COVID-19 – as well as other major coronaviruses, including those that caused the first SARS epidemic in 2002.

The studies in mice, rabbits and guinea pigs [...] found that the vaccine candidate provided a strong immune response against a range of coronaviruses by targeting the parts of the virus that are required for replication.

Professor Jonathan Heeney from Cambridge’s Department of Veterinary Medicine, who led the research, [said] “We wanted to come up with a vaccine that wouldn’t only protect against SARS-CoV-2, but all its relatives.”

A key cold medicine ingredient is basically worthless

The FDA’s 16-member advisory panel unanimously voted yesterday that oral phenylephrine, a common active ingredient in cold medications, is no better than a placebo for treating congestion.

The call by the panel sets up potential FDA action that could force the removal of certain over-the-counter medications containing the ingredient — including certain formulations of Mucinex, Sudafed, Tylenol, and NyQuil — from store shelves.
But FDA may hold off for many months, pending contested findings by drug makers and other considerations.

Data

Newer data from studies the panel says are more consistent with modern clinical trial standards showed phenylephrine simply “was not significantly different from placebo” in the recommended dosage, including trials from 2007 that the FDA had reviewed when considering the drug after a citizen petition prompted it to do so.

Bioavailability

The panel cited the drug’s low bioavailability, a term referring to qualities that allow the drug to be absorbed by the human body, as the main reason the drug should be removed from the market.

Jennifer Schwartzott said the drug “should have been removed from the market a long time ago,” while Dr. Stephen Clement said that although the drug itself isn’t dangerous, its usage by patients should be considered unsafe because it potentially delays actual treatment of disease symptoms.

Alternative

The panel cited pseudoephedrine as an effective alternative though while it’s technically available without a prescription, you must talk to a pharmacist to get it because, in large quantities, it can be used to make methamphetamines.

I've just started switching my medication and it's been pretty bad for me. Brain zaps are very frequent and I'm crying a lot. I'm struggling.

I've been trying to find out what other people's experience has been like when they switch meds. What is normal and what isn't. People who relate to brain zaps and how they deal with it. Are brain zaps even considered a real thing?

What has your experience been like?

This topic allows no mention of means to obtain drugs or endorses the use of it. It only asks for people who have experiences they are willing to share.

I'm referring to recreational and/or illegal substances.
