Bolivia says they will start clamping down March 2, they haven't yet.

Things are in flux, so getting a YF shot before going anywhere in South America is a good idea.

I used to be Cabin Crew about 10 years ago and I flew to countries where Yellow Fever cards were required and all I can say is this, get your yellow fever card. Emigrations are ANAL about it...and I mean completely ANAL. It is MUCH better to get the vaccination and not need it than have to go through all that hassle.

Had a passenger once that was on my flight back because he didn't have his yellow fever card.

According to World Health Organization, Ecuador will require a yellow fever certificate because I've been in Ecuador.

Or maybe Colombia will require a yellow fever certificate because you've been in Colombia ?

I've gone repeatedly over the Colombia - Ecuador border and never been asked for proof of vaccination, though not in the past year.

Copa started denying boarding to Bolivia on Feb 9th after the DGAC circular on 1st Feb. Then it looks like DGAC lifted it again on 13th Feb to give the Health Authority time to get their act together.

Mendocinateacher2, do you know if this is what is due to come back in again on March 2nd?

You can also get the YF vaccine free at the main public health clinics in Ecuador. They sometimes charge $10 for the international vaccine certificate, sometimes not. A single YF shot is good for life now as well.

For anyone who is interested you can follow the DGAC announcements here:

Although by this date, you have already visited our country, there are some topics in your question that need a reply.

Many tourists come daily to Peru with a kid for around 9 years old and even yunger. You just need to verify which activities would be fit for him/them. For example, which hiking would be fit for him.

About Vaccinations, it is reccommended the yellow fever and even though you can take it at Lima Airport, the effects takes 10 days, that is why it should be taken at your country. If it is difficult to get it, remember it is only a reccommendations, and it is not a requirement to enter to Peru. We have not had any cases since 25 years ago.

The YF certificate is causing problems with the new WHO guidelines

I have had several YF vaccinations in my lifetime & the last one was due to expire on 18th December 2016. Knowing that there are problems with the new guidelines I went off to see my Tropical Diseases doctor. He was an absolute saint and issued an new card, stamped it, signed in & filled in a new vial number, which never saw my arm!!!

I am now valid for another 10 years, having not had the vaccine but having had them since 4years old, probably better protected than most!

Great report though, thanks!!!

Note that the YF vaccine needs at least 10 days to become effective.

I crossed the border yesterday and I think it will be very useful to share my experience as reading around it seems a very scary one and impossible to avoid the bribes. IT'S NOT!!
For me it was important to do so because
condoning the corrupt behavior reinforces it, causing the scam to gradually worsen and become more problematic over time.

As proof of that until last year reaching the border from Nadasang (the village you arrive from don dhet) was possible by local bus of 20 min at the cost of 16000 kip (1,6€), now the police has taken control of it and forbids locals to bring tourists to the border with high fines. So the only option is a shitty bus for 8$.
At the border the first thing is to get the stamp out, they ask 2$ to do so with no legitimacy at all. I said that the embassy told me I didn't have to pay anything and anyway I didn't have the money, the guy didn't stamp my passport and while playing with his phone said "no embassy, your problem not mine", definitely the most unfriendly lao person in 40 days. After trying to gently reason with him and not managing, although all I felt like was reducing him to dust, I simply left my passport on his desk, quietly sat and waited showing no rush at all, he seemed to ignore me but I saw him taking my passport. After 15 min I got my stamp.
I walked through the border and reached the Cambodian immigration office where first they tell you to get the health check: if you have the international vaccination doc it's free if you don't they ask you 1$ to give you a phone number to call if you get ill. I said again that the embassy said it's not compulsory, but a guy with sunglasses, not an officer kept shouting "no check no visa" and I totally ignored him until he gave up. Some people instead of the vaccination paper showed an insurance card and didn't pay either. This paper is not even required at the immigration office.
After this I filled the application for the visa and handed it to the officer, again he asked 35$ (there is no written sign of the price) and I said the price was 30$ as the embassy said and that I didn't have more than that, again he shouted and gave me back my passport. After around 15 min I went back and kindly tried again, this time he came out of his cubicle and said to follow him. Here comes the interesting part, with dozens of people in line he went casually outside telling me to follow him, that he could help me. He went to his very nice toyota pick up 20 meters away to 'take his glasses' so we where out of the sight and on the way back he took my passport with the 30$. He went back into his cubicle telling me to sit on a chair closeby. In this way he could check on me and make sure I didn't tell anybody else (of course that was what mattered the most to him). After quite a while it was done and I could go to get the stamp and give my fingerprints.
I realize it's nothing more than a stubborness battle, the most persevering wins.
It took long but not much longer than anybody else, there were people whom applied before me and left after. There must have been more than 100 people and I didn't hear or see a single one arguing or refusing to pay. What was also surprising/sad was the reaction of them even after seeing my behavior and result, I'm not sure whether it was unjustified fear or not willingness to be bothered.
I also wonder how it would be if many all together refused to pay, what could they do after all? Nothing of this is illegal, they have no weapons, they only take advantage of tourists ignorance on the subject.
Just for those whom think that after all their salary is low, whit this scam only in one day they made 500 $ (if there were only 100 people) to share among the 4 officers I saw, that makes it 125$, more than many people's daily pay in Europe but life expenses are 10 times less.
I hope this will make people less afraid and that many more will do the same.

I read on another thread that you can get this vaccination free in Peru. Check it out?

Just a random thought - I enter via flight to La Paz from Cusco in June, so am trying to clarify this now.
