First, a division of the University of Oxford is the developer of this vaccine - not AZ. AZ has partnered with the University of Oxford to mass produce their vaccine.

Fingers toes eyes and everything else crossed! Thx. Marie Marie- I am not in a position to comment on anybody's specific medical situation nor am I qualified. It is highly recommended to discuss everything with your oncologist once the approved vaccine (or vaccines) is known. As for shingles - see below. There is a non-live version (Shingrix) now to discuss with your doctor and oncologist to see if appropriate for you. Go to this link: https://www.vaccines.gov/basics/types Here is some general background on viral vaccine types and how they apply to COVID vaccines being tested: 1) Live attenuated vaccines- a similar but much weakened live virus as the one you are trying to prevent- but altered to make it safe for most people but still induces a strong protective immune response. Examples here are MMR vaccine (Measles, Mumps, Rubella) and Chickenpox vaccine. There is a live-attenuated influenza nasal spray vaccine too. Note that the "older" Shingles vaccine Zostavax is in this category. 2) Inactivated vaccines- a "killed version" of the original virus. Influenza vaccines use this technology. 3) Subunit vaccines (non-live) - uses pieces (antigens) of the virus usually formulated in a special solution (adjuvant) to produce a required immune response. Additional booster shots are usually necessary. Hepatitis B vaccine. Note that the newer Shingles vaccine Shingrix is in this category. There are versions of COVID vaccines being tested that use the purified SPIKE protein as a potential subunit vaccine 4) Vectored vaccines and RNA/DNA vaccines - new categories lumped together here for brevity. In general they have been around for quite some time but not used (yet) in approved human preventative vaccines. The lead Oxford/AZ vaccine uses a replication-deficient (so "non-live") chimpanzee adenovirus (another type of common cold virus) that has been engineered to carry the coronavirus SPIKE protein. A human adenovirus version is being tested in China (CanSino) and is partnered with J&J. The Moderna vaccine uses purified pieces of the coronavirus RNA (non-live) delivered to cells in fat-like particles (liposomes). This vaccine is taken up by cells which then make the coronavirus SPIKE protein. Pfizer and BioNTech have a similar version of this RNA vaccine. 5) There are literally over 100 different vaccine approaches to COVID moving forward using versions of these technologies.

We will see though, as more data comes out, as this is a novel way of making a vaccine. A brilliant novel way for many reasons. You ask the right question. This will be a true test for worldwide regulatory authorities in the business of approving new vaccines. It is a muddy area. Are viral-vectored vaccines like the Oxford vaccine live if they do not carry their entire native genome and also cannot replicate? Or are they considered inactivated? These vectored approaches have been around for years actually. The debate has raged for years. Some have been used in oncology therapeutic vaccine approaches. None have been approved in large scale healthy adult populations (yet). Ebola vaccine from Merck which uses a vector approach called VSV has been used in limited areas in humans with success. They are developing a COVID vaccine using this same technology. This will all be fascinating (to me anyway!). Link to comment Share on other sites More sharing options...

madmacs Posted July 31, 2020 #258 Share Posted July 31, 2020 With cases starting to rise again in the UK, our Chief Medical Officer has suggested we have reached the limit of how far restrictions can be lifted, indeed they have been ramped up somewhat. I really can't see cruises happening until folks are vaccinated. That will almost certainly take us into next year. We are due to go on a cruise in March which I now rate as at best 50/50/ Link to comment Share on other sites More sharing options...

I agree and believe from everything I read that it will be by December of this year. The only problem is that 28 to 30% of people polled in the US say they will never take the vaccine. I hope that the travel industry as a whole will require anyone traveling outside the US by auto, air or ship have a certification of being vaccinated or not allowed to travel. A simple stamp on passports could accomplish the goal of proof of vaccination. Link to comment Share on other sites More sharing options...

But we agree, the cruise lines should require proof of vaccination in some form or fashion and also to continue to do temp checks prior to boarding. 1 Link to comment Share on other sites More sharing options...
Rare foodsvcmgr Posted August 1, 2020 #262 Share Posted August 1, 2020 Couldn’t agree more - let the anti-Vaxers stay home. That will provide some greater margin of safety if everyone on the ship and plane have been vaccinated and are required to present proof of same. Everyone has a choice, I choose to be vaccinated and I choose to cruise. 2 Link to comment Share on other sites More sharing options...
pumpkin 11 Posted August 1, 2020 #263 Share Posted August 1, 2020 I wouldn't get the vaccine because I know I'm not in a high risk category and I will recover. It should for the older people and people with underlying health conditions. Getting a vaccine doesn't mean you can't still spread it, which is what all of our measures are centered around now.

I know I shouldn't take the bait, but sometimes I can't help myself. First of all, you absolutely can't know that you will recover, and even if you do you may have long-lasting damage to your heart or other organs. There have been a number of news stories about perfectly healthy individuals with no underlying conditions who have died from the virus. So your chances of recovery may be better, but unless you have a crystal ball you cannot be sure you will recover. Secondly, there are a number of people who cannot take the vaccination due to health issues or being newborns. If you catch it you are putting their lives at risk by not being vaccinated. It's sad you could live with that on your conscience. I know I couldn't. 1 Link to comment Share on other sites More sharing options...

A vaccine just makes the “sickness” Portion less severe so you won’t die hopefully. Doesn’t stop the virus from showing up in some form or you being able to spread it. The vaccine just makes it less severe so hopefully people won’t die from it. If you cannot get the vaccine because of the risk of the after effects than I can’t help you you’re on your own and there is no government policy that will help you.

I usually don't bite on these, but you have no idea what you're talking about. The first endpoint in the vaccine trials is recovery of the virus. So if the vaccine candidates, or any of them, succeed at that, then the virus won't show up and you won't be able to spread it. The secondary endpoints are disease severity. You can find all that information at clinicaltrials.gov. It's actually mostly in English, although it certainly helps if you understand science. And, yes, you getting vaccinated can help people who can't. 2 1 Link to comment Share on other sites More sharing options...

Oh great job media you finally got one! Let’s focus on the hardest cases because the phrase “hard cases make bad law,” isn’t true here at all! 😉 I keeping all these ridiculous suspicions about covid... “maybe”... maybe covid 19 will make you unable to walk and you’re going to hop around on your knees for the rest of your life... MAYBE. Point two, you’re argument about “continuing to spread it without having a vaccine,” is first of all is pure conjecture. Secondly, the vaccine doesn’t stop you from being able to spread Covid 19, just helps with lessoning the symptoms so you hopefully don’t die.

Covepointcruiser Posted August 1, 2020 #269 Share Posted August 1, 2020 For the Moderna trials in the U.S., 300,000 have signed up with only room for 30,000. I hope they have no problems getting through this phase. I hope that those not getting the vaccine when it’s available are denied boarding at least until this gets under control.
