A country will require an official international vaccination certificate. Some Central and South American countries give free or low cost vaccinations, but require a fee if you want a certificate. An individual border official might accept a clinic note that you got the shot, but I doubt it.

Do get the shot for Brazil. There is currently an outbreak in the Sao Paulo area. Health authorities have acted quickly to get it under control, but Brazil has a habit of being very vigilant about inspecting certificates during an outbreak.

There is currently a worldwide shortage of YF vaccine. You may have to call around to find a clinic that has it. Sometimes, only specific government clinics will issue certificates.

Thanks for the ideas everyone! Lofgreli have you found an option yet?

We decided to head to Java on the 21st, it just seems easiest most appropriate for us as first-time visitors in Indonesia. Bromo, Ijen, Semeru, Sukawade all seem pretty interesting and we can even take the ferry.

I would love to see Sumba, Sumbawa, and Flores though, but maybe at a later point. We also don't haven't got rabies vaccination or malaria prophylaxis so Java feels a bit safer.

Guys, now that you know our itinerary... would you recommend vaccinations?

I see daily updates on the Ebola situation, but I don’t see a reason to post every one. Here is the Friday, June 8 update. Experts are now very cautiously saying that maybe the outbreak is winding down and that the use of the experimental vaccine may be a big factor.

The epidemiological situation of the Ebola virus disease dated 6 Jun 2018:

• a total of 62 cases of haemorrhagic fever were reported in the region, including 38 confirmed, 14 probable, and 10 suspected;
• 1 new case confirmed to Iboko. This is a known contact of a probable case who died on 20 May 2018;
• 5 new suspected cases, including 2 in Bikoro and 3 in Wangata;
• 4 samples were negative;
• no deaths reported today [total of 27 deaths; 13 of them among the confirmed cases];

Epidemiological analyzes have identified contacts living in nearby health areas in Bikoro and Iboko. These contacts are followed and advised to limit their movements during the entire follow-up period of 21 days.

Remarks

• Negative tests are systematically removed from the summary table.
• The category of probable cases includes all reported deaths for which it was not possible to obtain biological samples for laboratory confirmation.

News from the Ebola response
Vaccination

• Since the launch of the vaccination on [21 May 2018], 1826 people have been vaccinated, including 673 in Mbandaka, 398 in Bikoro, 725 in Iboko, and 30 in Ingende.

Partnership

• This Fri 8 Jun 2018, a team of Chinese experts will arrive in Kinshasa to assist the Congolese health authorities in the response to Ebola virus disease. Like other international experts who come to support the Congolese experts, they will participate in the various commissions set up to manage the response.
• It is also worth mentioning that under Congolese legislation, any use of experimental vaccines must be authorized by the Scientific Committee and the Ethics Committee. To date, only the rVSV-ZEBOV vaccine has been authorized by these committees as part of the current Ebola outbreak.

Some strange comments here, refering to my previous posts that apparently get misinterpreted.

For better understanding, two examples from one of our recent trips:

Earlier this year we travelled to Mozambique. I took antimalarians (doxycycline), as did my partner. Mozambique is a malaria risk area and we travelled in the end of wet season which increased the risk. I didn't need to think twice, it was a smiple decision. I wouldn't take unnecessary risks.

When we arrived at Maputo airport we had to take yellow fever jabs to be let into the country. US$50 each. Actually, we didn't mind as the vaccination is valid for lifetime. But taking it in Maputo wasn't necessary. It was an arbitary decision of the aiport doctor, who said, that we were arriving from Addis Abeba, and Ethiopia is on the list as risk area. It didin't matter that we had only a two hour stopover in Addis, on our way from Europe. They earned US$100 for a five minute service.

Anyway, as I mentioned before, you don't need to get vaccinated or take tablets only because you travel outside Europe. Consult a specialist doctor and make an informed decision, instead of doing it just in case, as many seem to do.

Actually you won't need the second Kenya visa, there is an agreement between East African Community countries that you can make a short trip to another EAC country and your visa will still be valid on your return. So your original Kenya visa will still be valid when you return to Mombasaj

PS you will need a Yellow Fever vaccination certificate when traveling between Kenya and Tanzania

A note to all those crossing the border at Noé/Elubo: at this border crossing the Ivorian authorities require the meningitis vaccination as obligatory. As I didn't have it, I had to take it on the spot at a "centre de santé et de hygiène" for a fee of 2500 cfa.

Dinero

But they are not particularly expensive, especially when most last numerous years. Seems a small price to pay for maintaining your health (kind of priceless to most people) and avoiding the small possibility of wasting your holiday on a hospital bed. It should just be factored in to the price of travelling. It's not so different to travel insurance in that it's something you are paying for that is 99.9% of the time not going to help you in anyway. Speaking of which if you pick up a disease that your government travel advice says you should get vaccinations for when traveling to that country is your insurance valid?

WHO says that old certificates are still valid, and that no traveler has to be re-vaccinated. Any country that has signed up to IHR is legally obliged to recognise it. It's not optional. Bolivia, like most countries, is a signatory. (The country list is here http://www.who.int/ihr/legal_issues/states_parties/en/).
